Sometimes, having too many of these devices in one part of the house can overwhelm the electrical circuit too.

3. Check The Wiring

Next, you are going to take a look at the connections.

This is going to start at the breaker panel to see if something has been damaged when the overloading took place.

Look at each connector in the breaker panel.

You will also want to take a look at the connectors running into the circuit throughout the house. This includes wiring that is damaged or showing signs of being burnt or frayed.

These wires should be replaced.

4. Reset The Circuit Breaker

Once you are sure everything is good to go, you will want to reset the circuit breaker.

The goal is to make sure you are toggling the tab back on at the breaker panel. This will allow power to flow back to that part of the house whether it’s the day or night.

You will want to be patient when doing this and test the circuit as soon as you can.

If the issue is fixed, the circuit breaker will not trip anymore.

Final Thoughts

These tips will go a long way if a circuit breaker trips at night.

If a circuit breaker trips at night, the most likely cause is overloading due to too many appliances or devices connected to the circuit. To fix the issue, turn off the power supply, inspect the wiring, reduce the load on the circuit by disconnecting appliances/devices, and then reset the circuit breaker.

This will ensure the problem goes away and the circuit breaker does not trip at night.

This is important when you want to do things the right way and ensure the circuit doesn’t get ruined at a deeper level.

What Causes Circuit Breakers To Trip At Night?

There are several possible causes of a circuit breaker tripping at night, including an overloaded circuit, short-circuiting caused by faulty wiring or appliances, incorrect wiring connections, or even age-related wear and tear on the wiring itself.

It is important to identify which of these is causing your circuit breaker issues before attempting any repairs, as this could result in further damage if done incorrectly.

Steps To Take Before Fixing A Circuit Breaker

A circuit breaker is an electrical switch that is designed to trip or break the circuit when it detects a short circuit or overcurrent.

Circuit breakers also help protect electrical wires from becoming overheated. A circuit breaker can be manually reset, or it can automatically reset itself after a fault is detected.

The circuit breaker can be reset by physically pushing the button to trip it or by turning the breaker switch off and then on again.

To reset a circuit breaker, follow these steps:

Shut down the circuit breaker

To avoid electrical shock, turn off all power sources, including the main electrical panel and any electrical devices. Then, shut off the circuit breaker that controls the circuit that has tripped.

Identify the circuit

The circuit breaker that controls the circuit that has tripped should be clearly marked with the circuit name and number. This information can help you identify the breaker that tripped.

Check the circuit breaker

If the circuit breaker is tripped, it will appear either in the “on” or “off” position. If the circuit breaker is in the “off” position, try flipping it to “on.” For circuit breakers that have two positions, such as “ON” and “OFF” or “ON” and “AUTO-RESTART,” flipping the circuit breaker to the “AUTO-RESTART” position will reset it.

Call a qualified electrician if the circuit breaker is still not reset.

The circuit breaker may be faulty, or the switch mechanism may be dirty or damaged. Faulty circuit breakers should be replaced immediately by an electrician.

How To Reset A Tripped Circuit Breaker

If you find that your circuit breaker has tripped, it is important that you reset it correctly in order for your electrical system to operate properly again.

Turning off all power sources connected to the affected area (such as unplugging appliances) is the first step, followed by flipping the switch located on the side of the panel box.

Make sure to wait 10 seconds after flipping the switch before restoring power; this gives time for any excess current flowing through wires to dissipate.

If, after resetting your circuit breaker, it continues to trip, then move onto other possible solutions outlined below.

How To Check For An Overloaded Circuit

An overloaded circuit is one that is carrying more current than it’s supposed to.

Overloading a circuit can cause a fire or an electrical shock. For this reason, it’s important to check for overloaded circuits regularly.

Unfortunately, checking the circuit for overloading can be complicated and dangerous if you don’t know what you’re doing. Fortunately, there is a simple and safe way to check if a circuit is overloaded: use a multimeter.

How To Identify And Replace A Faulty Breaker

Breakers are usually found near electrical panels or fuse boxes.

Each breaker has a number that indicates the amount of electrical current it can handle. If more electrical current passes through the breaker than it’s designed for, the breaker will break due to excessive heat.

Breakers break due to heat when they’re overloaded or after a long period of overuse. To test whether a circuit breaker is broken, find the breaker and flip the lever to the off position.

If the breaker doesn’t turn off, it’s broken and should be replaced immediately. Next, verify that the circuit that you’re trying to turn off is turned off.

To do this, turn off the circuit breaker in the electrical panel or fuse box for the circuit and flip the breaker to the off position. If the breaker doesn’t turn off, the circuit is broken and should be replaced.

Finally, locate the breaker and flip the lever to the off position. If the breaker still doesn’t turn off, it’s broken and should be replaced immediately.

Troubleshooting Tips For Tripping Circuits

If, after replacing a faulty switch, you find that your new one continues to trip, then there may be another underlying issue, such as:

• Loose wiring connections or even old/faulty wiring itself
• Start by inspecting each wire connection inside your panel box making sure they are tight and secure.

Common Causes Of Circuit Breakers Tripping At Night

A circuit breaker is designed to trip when it detects a dangerous amount of electricity.

For example, if a short circuit occurs, the circuit breaker will trip and disconnect the electricity to prevent further damage. However, some circuit breakers sometimes trip for no apparent reason.

This can be caused by a number of reasons. For example, if your circuit breaker is old, it may no longer work correctly.

Furthermore, if your circuit breaker is located in a humid environment, it may become corroded and malfunction.

However, the most common cause of a circuit breaker tripping at night is having too many appliances plugged into one circuit.

Having too many appliances plugged into one circuit can overload the circuit and cause the circuit breaker to trip.

Therefore, it’s important to always unplug unneeded appliances or add more outlets to your circuit to prevent your circuit breaker from tripping at night.

In conclusion, there are three reasons why circuit breakers trip at night.

First, when electricity is flowing, the electricity can heat up the wire in the breaker box. This heat can cause the breaker to trip.

Second, when the power goes out, the breaker must be reset. This reset process takes a few seconds, allowing electricity to flow into the wires again.

Finally, circuit breakers trip at night because higher amounts of electricity are used to heat the home at night.

These three reasons explain why circuit breakers trip at night and what can be done to prevent them.

Why Is Circuit Breaker Keeps Tripping?

The circuit breakers in your house or building are there to protect you from the dangers of electrical faults. Still, it can be pretty stressful when one of those breakers repeatedly trips, no matter how many times you try to turn it back on.

When your circuit breaker trips, that means there’s an electrical fault in the circuit it protects. You can fix it by troubleshooting all appliances and electrical components on that circuit. For example, a device is likely faulty, or there’s damage to wall sockets and electrical wiring. Once you resolve the root cause, you can turn the breaker back on.

Unfortunately, troubleshooting a tripping circuit breaker isn’t always straightforward. Don’t worry, though. This guide will teach you to fix the problem much more effectively.

Is It Dangerous If A Circuit Breaker Keeps Tripping?

Table of Contents

Yes, it’s very dangerous if you have a circuit breaker that keeps tripping.

To know why you must first understand the purpose of that circuit breaker. You see, it’s very dangerous when too much electrical current flows through a circuit. So, a circuit breaker is added to that circuit to prevent that from happening.

Excessive current in the circuit will cause the breaker to trip. As the name suggests, that will break the circuit and stop the flow of electricity entirely.

However, if your circuit breaker keeps tripping, that means there’s an ongoing electrical fault somewhere on that circuit. 

For example, there could be a fault in the appliance or their wiring.

Until you fix the fault and stop the circuit breaker from tripping, you run the risk of:

• Electrocution to anyone handling any part of that circuit.
• Electrical fires could spread throughout the house or building.
• Damage to any appliance on that circuit, requiring expensive replacements and repairs.

How To Find What Is Tripping My Circuit Breaker?

Finding the root cause behind your tripping circuit breaker will require a bit of detective work on your part.

Use this 3-step process to find the root cause:

Step 1: Identify The Affected Circuit

First and foremost, you must identify the affected circuit, which the tripping circuit breaker protects.

To do that, start at the main electrical box and open the panel. That’s where you’ll find all of the circuit breakers for your home or building.

In some cases, you’ll find that each circuit breaker has a clear label telling you what it’s for. If that’s the case, you’ll have a much easier time finding the root cause of the problem.

However, if there are no labels, you’ll have to test them manually. Reset the circuit breaker and see which appliance or part of your house turns on. Pay attention to when it trips and see which parts of the house no longer have electrical power.

Once you identify the affected circuit, you can then troubleshoot the electrical components and appliances in that part of the house.

Step 2: Check All Electrical Outlets And Appliances On That Circuit

Let’s suppose that the tripping breaker is for your kitchen’s electrical circuit. In that case, you’ll have to check the electrical components and appliances in that part of the house.

What you’re looking for are signs of electrical damage or faults. 

For example, look for burning smells or burn marks on your appliances and plugs. 

Step 3: Test Individual Appliances And Look For Patterns

You’ll have to go through a lot of trial and error for this troubleshooting process. For example, suppose you suspect that a specific appliance is causing your breaker to trip. In that case, it’s best to test it on another circuit.

For example, plug your toaster into a wall socket at another part of the house. When that causes a different circuit breaker to trip, you’ll know that the appliance is to blame.

Besides that, look out for patterns when the breaker trips. For example, do you notice it tripping whenever the fridge compressor turns on? That’s a clear sign that you should get a technician to troubleshoot the fridge instead.

How To Fix A Breaker That Keeps Tripping?

Sometimes, it’s not an appliance that’s causing your circuit breaker to keep tripping. So once you rule out any problems with your devices, here are a few other things to consider.

Why Does My Breaker Keep Tripping With Nothing Plugged In?

Try not to get frustrated when your circuit breaker trips even with nothing plugged in. Once you’re sure that none of your appliances are on, you’ll have to troubleshoot for:

• Short circuits caused by problems with your electrical wiring.
• Excessive currents, like from power surges during thunderstorms .
• Ground faults, when a live electrical wire touches the ground.
• Faulty circuit breakers, if you have old circuit breakers at the end of their useful lifespan.

Troubleshooting the above can be pretty risky if you’re not sure what you’re doing. So, again, don’t be afraid to contact an electrician to do it for you.

Why Does My Circuit Breaker Trip Only At Night?

As you’ve seen in earlier parts of this guide, troubleshooting a tripping circuit breaker involves trial and error, as well as spotting patterns.

So, if your circuit breaker keeps tripping at night, focus your attention on appliances that only run during that time.

For example:

• Do you have automatic lights that only turn on at night?
• Do you have an HVAC (heating, ventilation, air conditioning) system that runs at night?
• Do you have computer systems or similar equipment that run at night?

Once you narrow down the appliances that might cause the circuit breaker to trip only at night, troubleshoot them one at a time using the same steps described above.

For example, you can plug the appliances into different circuits in your house to see if they trip other circuit breakers instead.

Why Does My Circuit Breaker Trip After 30 Minutes?

After resetting a tripped circuit breaker, you might find that there’s a slight delay before it trips again. That delay could be 30 minutes or even a few hours before the breaker predictably trips again.

The reason that happens is that the circuit is overloaded but only barely over the circuit breaker’s limit. In other words, there is an electrical fault, but not enough to instantly trip the circuit breaker.

As a result, the breaker is constantly on the verge of tripping. Still, it often takes a bit of time before that happens.

So, whether your circuit breaker takes 3 minutes or 30 minutes to trip, you must troubleshoot the circuit using the same steps described above.

In short, you must check for electrical faults in:

• All appliances plugged into that circuit, like lights, TVs, kitchen equipment, and anything else.
• All power sockets and switches on that circuit, including wall switches and wall outlets that you plug appliances into.
• All electrical wiring for that circuit, which might have suffered burns or been chewed through by pests.

How Do You Reset A Tripped Breaker?

Resetting a tripped circuit breaker is very straightforward.

First, you must understand that a standard circuit breaker has 3 positions:

• ON: On one side, you have the ON position. That means the electrical current will flow through the breaker and the circuit.
• OFF: You can push the breaker to the OFF position on the other side. That will stop any electricity from flowing in the circuit.
• Center: More importantly, you have the center position. When your circuit breaker trips, it will not go to the OFF position. Instead, it’ll go to the center to indicate that it tripped and was not shut off on purpose.

Do not push the switch from the center to the ON position to reset a tripped breaker. Instead, do this:

• Firstly, move the switch to the OFF position.
• Secondly, move the switch all the way to the ON position.

When The Tripped Circuit Breaker Won’t Reset:

When you try to reset your circuit breaker, but it trips instantly, that’s a telltale sign that there’s a short circuit.

Do not try to force the circuit breaker to stay on. Instead, you must troubleshoot the circuit and fix the root cause first.

When The Breaker Keeps Tripping After Reset:

Suppose you successfully reset the circuit breaker, but it trips soon after. In that case, you likely have a ground fault in the circuit.

That’s when the electricity flows straight to the ground instead of going through the circuit normally. Again, you must resolve the root cause of this issue before you can turn your circuit breaker back on again.

What Causes Circuit Breakers To Trip?

• April 2, 2024

If your circuit breakers keep tripping, there’s no need to stress. This is a typical situation. Below, you’ll find details on the reasons behind this and tips for avoiding it going forward. Get a handle on your circuit breaker issues!

Table of Contents

Understanding Circuit Breaker Tripping

Circuit breakers are protection devices for electrical circuits. When too much current passes, the breaker trips, stopping the flow of electricity and preventing damage. This can be caused by faulty wiring, too many appliances on one circuit, or a ground fault.

Overloading can cause tripping. This happens when too many devices are connected to a single circuit. Heat builds up in the wires, which can start fires or cause damage. To prevent this, distribute loads across multiple circuits and don’t connect too many appliances to one outlet.

Short circuits also lead to tripping. This happens when two wires with opposite charges come in contact or when a wire touches something grounded. This causes an immediate surge in current that triggers the breaker. Check for exposed wires or insulation damage, and call an electrician if you spot any signs of trouble.

Ground faults can also cause tripping. This happens when there’s an unintentional connection between a live wire and a conductive surface. Install GFCIs to avoid this.

In short, know what causes circuit breakers to trip. Identify potential hazards like overloading, short circuits, and ground faults. Take steps to prevent accidents and ensure your electrical equipment is safe. If you’re unsure how to handle electrical problems, call a licensed electrician.

Overloading Causes

Circuit breakers trip to stop overheating, electrical fires, and damage to electrical parts. Plugging in too many devices can cause the circuit to become overloaded, so the breaker trips to cut off the power.

Short circuits are like a blind date gone wrong. They can be explosive, and often end in disaster. This happens when a hot wire comes into contact with a neutral or insulation/water. This throws off the electric balance, causing danger and tripping.

Short Circuit Causes

A short circuit happens when a low-resistance path appears between two points in the circuit that aren’t usually connected. This can cause too much current to flow, making a circuit breaker trip. Insulation or wiring damage, faulty appliances, and circuit overload are the most common reasons for a short circuit. It’s critical to identify and fix the root cause quickly to avoid electrical fires and other dangers .

When too much power passes through a circuit, the circuit breaker will automatically turn off. It’s designed to protect wiring and guard against electrical accidents . But if the breaker trips regularly, there may be underlying issues that need investigation and repair. Often times, this means upgrading or replacing components.

Sometimes short circuits are caused by human error or wear and tear. But they may also come from design or installation problems. Planning and upkeep from local electricians can keep electrical systems running safely and appropriately for a long time. If your circuit breaker is tripping a lot, get an experienced technician to review your system and suggest solutions that match your needs and budget .

Overheating Causes

Circuit breakers are essential safety features. They stop electrical fires and protect your appliances. When overloaded, too much current flows, producing heat. This causes the breaker to trip!

Other factors can cause overheating. Damaged insulation on wires increases resistance. Loose connections add resistance and heat. High temperatures and poor ventilation worsen the situation.

It’s important to maintain and service the electrical system. Checks of all components will make sure they work efficiently. To avoid tripping, prevent overheating. This will reduce energy consumption and safeguard equipment. So, let’s learn about circuit breakers and how they deal with overloads!

Circuit Breaker Types

Circuit breakers are essential for any electrical system. They prevent overloaded and faulted circuits . There are different types of circuit breakers suitable for specific electrical loads.

See the table below for the different types of circuit breakers and their functions:

It is crucial to select the right type of breaker. Each one has its own advantages in specific situations. For instance, thermal circuit breakers are perfect for small appliances like hair dryers or irons . Meanwhile, magnetic circuit breakers are great for bigger loads such as air conditioners or refrigerators .

Remember, circuit breakers are like Beyoncé – they can handle a lot, but have their limits.

Circuit Breaker Ratings and Specifications

Circuit breakers are designed to protect electrical circuits from overloads. To ensure that circuits and appliances are safe, the ratings and specifications of circuit breakers need to be understood.

If a circuit breaker trips often, it may mean there’s an issue. It’s best to get professional help in these cases. Time to go on a hunt for your electrical wiring!

Troubleshooting Circuit Breaker Tripping

Circuit breakers can flip out for multiple reasons, like overloads , short circuits , and ground faults .

Overloads happen when too much electricity passes through the circuit, creating too much heat and tripping the breaker. Short circuits are when two or more wires touch, resulting in extra current. Ground faults occur when the power takes an unexpected route, like through a person’s body.

To figure out why your circuit breaker is tripping, it’s important to figure out what is going on and act accordingly. Inspections and maintenance can also help avoid future tripping.

Stop your circuit breaker from misbehaving with these prevention tips!

Preventing Circuit Breaker Tripping

A circuit breaker tripping can be prevented with understanding. When circuits are overloaded, breakers trip to avoid overheating and potential fires. Here are 3 steps that can help you prevent circuit breakers tripping:

• Know the electrical load – work out how many appliances & devices are connected to one circuit. Don’t overload them by spreading high-energy equipment across multiple circuits .
• Look after your appliances – ensure all your appliances & devices are in good condition, with no damaged cords or frayed wires.
• Upgrade your system – if you’re tripping breakers often you may need to upgrade the electrical system with higher capacity breakers or more circuits.

Plus, investing in surge protectors can also assist in preventing circuit overload and subsequent tripping of breakers. By following these steps you can make sure your home’s electricity runs safely and without interruption due to circuit breakers tripping.

Remember: these precautions will keep you from tripping more than just your circuit breakers!

Safety Precautions

Safety must be taken seriously when dealing with circuit breakers . Always switch off the main power supply before beginning work. Wear protective gear such as insulated gloves and boots to stay safe from electrocution. Never touch wires or components inside the box without proper training. Keep the area around the breaker box free from any flammable substances. Inspect breakers for damage or wear regularly .

Label each circuit breaker correctly . Test them frequently for functionality. This will help identify circuits quickly in case of an emergency. These precautions and practices ensure safety while dealing with circuit breakers. When in doubt, blame it on the circuit breaker – it’s always a good scapegoat for electrical woes!

Circuit breakers are essential components of any electrical system. They stop too much current flowing and thus, protect against potential fires . The most common cause for tripping is overload. But, other causes like short circuits and ground faults can also cause the breaker to trip. When it trips, there is something wrong that needs to be fixed right away.

Short circuits occur when two wires touch each other. This creates a low resistance path which allows a lot of current to flow with no load. Ground faults occur when the hot wire touches something incorrectly wired or with a damaged cord.

To prevent tripping, regular maintenance of the electrical system is needed. Keeping appliances in good condition, replacing worn-out cords and fixtures, and periodically checking for loose wires all help reduce the chances of tripping. In summary, understanding why the breaker trips and taking precautionary measures will keep you safe and save you repair costs.

Site search, why do circuit breakers trip.

Master electrician Heath Eastman shows host Kevin O’Connor everything he needs to know about why and how breakers trip.

Heath Eastman talks about circuit breakers. Heath shows Kevin O’Connor that while resetting these breakers is simple, these are complex devices that monitor and protect circuits. First, the two talk about the different sizes of breakers before moving on to the different types. Finally, Heath shows Kevin how to test certain breakers to ensure they’re working properly.

Circuit breakers exist to protect people, appliances, and homes from dangerous electrical current. However, few people understand why the trip and how they operate. Master electrician Heath Eastman shows host Kevin O’Connor why this happens, and even explains a few different types of breakers.

All About Electrical Systems

Breakers protect circuits.

When electricity comes into the house, it flows through the electrical service panel. From there, the electricity flows out through different branches in the house, each controlled by a circuit breaker. Should a branch begin to overload and overheat, the breaker will trip to prevent damage.

Breaker Sizes

There are two main sizes of breakers in a house: 15 amp and 20 amp. The amp rating explains how much current the breaker can handle before it will trip, and each requires a certain size of wire. Fifteen-amp breakers require a 14-gauge wire, while 20-amp breakers require a 12-gauge wire.

How They Work

A 15-amp breaker won’t necessarily trip the moment it experiences a spike above 15 amps. Many devices draw more amps upon start-up, and these breakers allow those temporary spikes. However, should the breaker sense elevated amperage for longer than is typical, it will trip to prevent the circuit from overheating.

GFCIs and AFCIs

Beyond circuit overload protection, there are other types of breakers that offer additional coverage. These include GFCI breakers and relatively-new AFCI breakers .

GFCI (ground fault circuit interrupter) breakers need to experience the same amount of current going out as coming back through the circuit. If the breaker experiences a drop in returning current, it assumes that the circuit is leaking, whether it be through a water source or a person. When this imbalance occurs, the GFCI trips immediately.

AFCI (arc fault circuit interrupter) breakers sense when the circuit, a device, or an appliance is arcing (the current is jumping from the circuit and onto something else or someone). When the breaker recognizes the arc signature, it trips immediately. These breakers are relatively new and look similar to GFCI breakers, but they’re becoming a code requirement in most locations.

How to Test Breakers

Homeowners, electricians, and inspectors can test their breakers. There are devices that users can plug into an outlet and replicate an error. These devices, known as AFCI/GFCI testers, can trip the breaker altogether or replicate a ground or arc fault, triggering the breaker. This is one of the best ways to ensure that a breaker is working properly.

When to Call a Professional

If a circuit is continuously tripping, or you know that it should be tripping and isn’t, be sure to call in a professional. An electrician will be able to determine the cause of the issue and make sure your circuit breakers and electrical system are safe.

Heath explains what a circuit breaker is, why they trip and how it protects a home. A circuit breaker is a device, installed in the electrical panel, that controls whether power can be sent from the panel through a circuit. Heath explains this ability is controlled by a switch that can be operated either manually—like when a person wants to interrupt power for service—or automatically, like a breaker trip.

He says power overloads, current “leaks”, and arcs are the three reasons that would cause a breaker to trip. A Power overload happens when a device is calling for more power than a receptacle , or a circuit is designed to provide. Current “leaks” are caused when current strays from the circuit for whatever reason, though it happens most commonly when moisture is present. Arcs can happen when the wire breaks down over time (due to overloads but also due to other factors, like animals chewing the wire and other decay) but what Heath sees the most is human error.

If a specific receptacle is consistently tripping the breaker, Heath advises to have a licensed electrician identify the problem to ensure the work is done safely.

What causes a circuit breaker to trip and how to deal with it

Table Of Contents

Your circuit breaker is an important safety element in your home. This is because it keeps your home safe in the event of an electrical fault . When your home's circuit breaker starts tripping, you will have to reset it back to normal. The circuit breaker is usually located inside your fuse box, either inside your garage or under your staircase. The primary use of your circuit breaker is to interrupt electric current when your home's electrical system becomes faulty. It does this so you can safely reset it and restore power in your home.

A circuit breaker is a safety device meant for protecting your home. Constant resetting and tripping, however, can become annoying for you. Therefore, it is essential to pinpoint why your breaker keeps on tripping . If you cannot get to the bottom of the matter, then having an electrical technician come by to do some diagnostics can save you a lot of unnecessary stress.

What is a Circuit Breaker?

All business premises and homes, including yours, have a switching device that that is very important. Generally, this switch cuts off power to protect your property in case of an electrical fault in the circuit. This electrical system is typically located inside a fuse box or panel located in an accessible location.

Most modern electrical systems come with a breaker that switches off automatically in case of any trouble. You can reset it back afterward. The older versions, however, were meant to blow if the system was faulty or overloaded.

A circuit breaker will cut off electricity flow in case your electric system is overly taxed. It does so to prevent overheating of electric wires. If left unchecked, it can lead to an electrical fire in your home. Therefore, a circuit breaker is put in place to control and protect your home or business power system and any devices which are connected to the system.

Circuit breakers can be managed either automatically or manually. If the electricity flow is very strong or overloaded in your home, a switch will be triggered and trip your breaker to cut off your electrical supply.

What Makes a Circuit Breaker Trip?

When there is an electrical fault which remains unattended to, your breaker will keep on tripping . It does so to prevent any damage to your home's circuit. An electrical fault is mainly caused by faulty electric components, excess electric current, or a power surge. Reasons for circuit breaker trips include:

Short Circuits

A short circuit is one of the leading causes of a tripping circuit breaker. You need to know that they are potentially very dangerous. A short circuit occurs when there is some fault in your electrical system , and a naked live wire gets in contact with a naked neutral wire, or one of your plugged appliances has faulty wiring.

When a short circuit occurs in your home, it means that the primary electrical resistance has been overridden, and there is too much current flowing through the circuit abruptly. When a short circuit happens, a lot of heat is generated in the circuit. As a result, your breaker will then have to shut off the circuit by tripping. When this happens, you might sometimes notice dark or yellowish discolouration around your circuit breaker. It is a clear indication of a short circuit. You should contact a licensed electrician to help you out immediately.

Ground Fault Surges

Short circuits and ground fault surges tend to behave similarly. However, ground-fault surges happen when a live wire comes into contact with a bare copper ground wire or the metallic outlet box connected to the ground wire. When this happens, an excess flow of electricity will generally occur, which in turn causes the circuit breaker to trip.

These kinds of electrical issues are not only inconvenient and dangerous, but they are also annoying. If your breaker trips often, it puts your home at risk of an electrical fire. Reaching out to electrical professionals to fix the issue can save both lives and your property. Therefore, try to be prompt.

Circuit Overloads

A circuit overload is a common cause for your breaker to trip. It usually occurs when you burden a particular circuit with appliances beyond the number that the circuit can handle. This excess burden on the circuit can cause it to overheat hence putting all the lighting features and electrical appliances at significant risk.

Your circuit breaker is meant to accommodate a specific capacity of electrical current. If, for instance, you run a tumble dryer and a dishwasher in a single circuit, you might end up drawing around 20amps of electric currents. If you do this in a circuit that can only accommodate about 15amps, the circuit overloads. To prevent your appliances from roasting and the wires from overheating, your circuit breaker will trip. This will protect your electrical appliances and save you from a lot of monetary trouble.

In such an instance, to prevent your breaker from tripping out frequently, you will have to redistribute your lighting features and electrical appliances in your house. Alternatively, you can call a licensed professional to upgrade your circuits.

Importance of a Circuit Breaker in Your Home

A circuit breaker in your home can be the difference between life and death. It is a very crucial part of the electrical wiring in your home as a safety feature. Circuit breakers keep the danger of electrical fires at bay in your home or business premises. Modern breakers work automatically as an electrical switch that protects your home's electrical circuits from potential electrical damage.

A circuit breaker is meant to detect any kind of fault and cut the system to hinder any further flow of electric currents in the circuit. If left unchecked, it can lead to a fire breakout. Even though circuit breakers are usually more costly than fuses, they are generally more preferred than fuses by most business owners and homeowners. Moreover, electricians and wiring experts also prefer them to fuses.

Choosing a Circuit Breaker for Your Property

Circuit breakers are available in various shapes and sizes. As a homeowner, you should seek the guidance of an electrician to choose what breaker suits your household. When installing a circuit breaker in your home, it is also crucial for you to have a conducive space to accommodate the installation.

People have their own requirements and needs. This means that you can choose any room in which to have your circuit breakers installed in. Whether it is in the kitchen, garage, living room, or even bedroom, the choice is yours.

What Should You Do When a Circuit Breaker Trips?

When the breaker in your fuse box trips, it is possible that either a single circuit or the entire circuit in your house is going off. Therefore, you must know what to do when your circuit breaker trips. It is crucial as you will be able to get your day back on track once again without the hassle of calling an electrician to come over and fix it for you.

When your circuit breaker trips at night, you might find yourself and your family in pitch darkness. Therefore, you must have an alternative source of light so that you can find your way around the house. You can either have a torch strategically located in your home or use your phone to illuminate your way around the house. It is also prudent for you to have some form of lighting when you go check the fuse box because blindly feeling inside the fuse box without light can be very dangerous.

Here are the steps to follow if your circuit breaker trips:

• Step 1: First, put off your electrical appliances. You must be prompt enough to turn off all electrical appliances that are attached to the faulty circuit. By unplugging off appliances connected to the affected circuit, you will be reducing the risk of another trip if you reset your breaker once again.

• Step 2: Proceed to turn off the master switch at the power board. This way, you will be cutting off electrical current to your home so that you can access the fuse box without any risk of an electrical shock.

• Step 3: Ensure you have a safety switch installed in your home: Your home should have a functional RCD safety switch. It is very crucial to have this switch to protect your family from electrical shock.

How to Prevent Your Electrical Circuit from a Potential Overload

In many areas of our lives, prevention is always better than finding a solution. Keeping a problem at bay is cheaper and easier than finding solutions to the problem. The same logic also applies to your house's electrical system. Therefore, to avert a potential circuit overload in your home:

• Do not plug in too many electrical devices in one circuit.

• Get a licensed electrician to upgrade your old circuits to meet higher electricity demand.

An Electrician Can Check Your Circuit Breaker

A circuit breaker is an essential component of your home's electrical system. It keeps you and your loved ones from potential harm in case of a faulty electrical system. A breaker that trips often can, however, become a nuisance. It is also an indication that you need to find an expert in circuit breaker services to come over and check out what could be the underlying cause.

Why Circuit Breakers Trip and What To Do About It

by Exquisite Electric | Last updated Nov 26, 2023 | Blog

Have you ever wonder why your circuit breakers trip? 

We when a circuit breaker in your electrical panel trips, it happens for a reason. , but simply resetting the breaker won’t solve the underlying issue and may end up causing bigger problems in the future. in this article, we will discuss 3 common reasons why your electrical circuit breakers trip and what you can do about it..

Post Takeaways:

• Circuit Breakers trip for a reason. Don’t reset them unless you know why they tripped in the first place
• Most if the time breakers trip because of an overloaded circuit
• Wires can touch  and cause a short for a number of reasons, including loose connections or improper installation
• Ground faults are often the result of the wire’s insulation breaking down or improper installation
• Ignoring the underlying problem and resetting the breakers could result in fire, hazard conditions, or electrocution risk

What is a ‘Trip’?

“Why are my circuit breakers tripping?”

This is a question we often hear when customers call us for help. Without performing an inspection it’s hard to know what the cause is, BUT a breaker ‘trips’ because it senses an abnormal power draw and shuts off the electrical flow.

By shutting off the circuit, your panel prevents overheating and a potentially electrical fire. So, if you have to reset the breaker frequently, you may have a bigger issue that needs attention.

So, What Causes a Circuit Breaker to Trip?

There are three main reasons why your circuit breaker trips: an overloaded circuit , a short circuit , or a ground fault .

Circuit Breaker Safety

At Exquisite Electric, we don’t recommend resetting any breakers without understanding why the circuit breaker tripped and shut off power in the first place.

Ignoring the underlying problem and resetting the breakers could result in fire, hazard conditions, or electrocution risk.

Be Safe. Call a professional e lectrician for help.

1. An Overloaded Circuit is Causing the Breaker to Trip

The most common reason for a breaker to trip is an overloaded circuit.

Usually, having too many appliances running on the same circuit is what causes the problem. These appliances are generally high power devices, such as air conditioners, hairdryers, or heaters.

In addition, if one of those appliances becomes overheated, it can cause the whole circuit to overheat, causing the breaker to shut off power.

Electrical Tips for the Home

What to do when a circuit breaker trips.

If a circuit breaker in your switchboard trips it can mean anything from one appliance going down to a whole section of the house being left in the dark. It pays to know how to reset one that’s fizzled out so you can get your day or night back on track, without having to call out the electrical services company. Here are a few things to remember when your circuit breaker trips:

Keep an emergency torch (and remember where this is)

If the circuit breaker trips and its night, then you’re in the dark. Use the flashlight function on your phone to find your way around the house. It’s also a good idea to have a torch on hand for situations like these, or at least matches and a candle. Even if you know where your electrical box is and feel confident you could do it with your eyes closed; it’s just not a good idea to go feeling around inside electrical boxes without a proper light source.

3 steps to follow when a circuit breaker trips

1. turn appliances off.

Always turn off appliances that are connected to the affected circuit. Your circuit breaker tripped for a reason. Having all your appliances on can do that. If this was the case when the breaker tripped, make sure you go around and switch off and unplug everything that’s connected to the circuit, otherwise it will be immediately loaded with power and may cause the issue to occur again.

2.Master switch

Once at the power board, turn off the master switch. Make sure you do this before doing anything else! This is going to cut all the power to the circuits, so if there is a fault it can’t hurt you while you are in the switchboard.

3.Safety switch

Make sure you always have a RCD safety switch installed and tested regularly. These are essential for houses to ensure that everyone in the house is protected from getting a zap! These will also be triggered if, while making the Christmas pavlova, the mix master burns out. If that is the case unplug all the appliances, see if they’ll work in another area of the house. If one of these appliances doesn’t work at all, it’s likely that this was the cause of the tripped circuit breaker. Don’t plug this appliance back in. See if you can replace it or have it fixed. ●

Ready to go again

Turn on the master switch. After all this fuss you almost expect a sort of powering-up noise to signal that you’ve done it. No such luck. Go back to your appliances and turn them all back on.

What causes circuit overloads?

One of the most common problems of tripping a circuit breaker is what we call “overloading the circuit”. Too much extra power consumption on one circuit could cause the breaker to trip.

This may seem like an inconvenience, but it’s a nice reminder that your circuit breaker is working. Using both thermal and magnetic tripping mechanisms, modern circuit breakers will cause a power outage, rather than allowing a circuit to overwork, catch fire, and burn your house down. Electrical circuits have a limit to how much electricity they can provide, so it’s also a reminder to consider the amount of appliances you’re powering.

Common causes include an extravagant nativity scene on your house during Christmas, excessive powering of air conditioning and fans during a heat wave or overloading a circuit with too many electrical devices.

If you notice your lights are dimming, buzzing, your outlets are warm, or your appliances are lacking power then you can catch a trip before it happens.

There are a few ways you can prevent a circuit overload: •Have an electrician rewire old circuits with new ones that can meet a higher electrical demand. •Avoid connecting too many devices to the one circuit. •Instead, share the load across different circuits. •

Back to life as normal again

Now go back to whatever it was you were doing before you were so rudely interrupted. Resetting a circuit breaker isn’t rocket science, and certainly doesn’t require an electrician. It’s a matter of preparation and keeping calm. If you’re uncertain of what the problem is after trying the above, or if you want a professional to look at it, just give us a call at (215)342-4353, we are always here to help. Plus we have on call electricians over the Christmas break, so even if it happens on Christmas morning, we can have someone there.

Circuit Breaker Trips same time every night

• Thread starter peter61
• Start date Aug 11, 2008

Users who are viewing this thread

• Aug 11, 2008

On the same line are three outside plugs, overhead bathroom light (75 watt)and vanity light in bathroom (three sixty watt light bulbs) and two outside lights (75 watts a light). On one outside plug are outside garden patio lights 12 watts a light and no more than ten lights. Nothing else plugged in to other two outlets and also outside motion detector light on same circuit. Motion detector light has one light that turns on and off and one set to motion. The switch that turns on the motion detector light that turns on and off also turns on and off another floodlight some 15 yards away. Problem statement. Circuit trips almost every night between hours of 1 and 6 am as bathroom lights work fine before going to bed and circuit trips by the time you get up. Have paid over 400 dollars to electricians who "investigated", replaced circuit breaker and still not fixed. Strange thing is that almost every single night the circuit trips. You can leave the bathroom light on throughout day and no problem, just trips at night. Have turned off all outside lights, did not turn on floodlights, unplugged garden lights and still tripped? Did replace vanity light as it was very old and problem went away for 2-3 weeks then returned all of a sudden. I am not electrician but fear my house is turned into Blair Witch Project. Bought a motion detector light replacement but have still not replaced as it may be a bear to get the old one off without some sort of idea motion detector light (and its on off companion) are likely the problem. Suggestions more than welcome.  

Electrical Contractor/Instructor

If you have paid an electrician $400 dollars I suggest you call them back and have them fix the problem or call your licensing board and have them get the electrician fix it. If you paid some maintainence man this $400 then you just wasted your money and still need to spend some to get a real electrician.

In the Trades

Sometimes there are intermittent problems which take a bit of trial and error and time to fix. One way to attack this problem is to disconnect portions of the circuit and see if the problem still happens. So if you have a circuit which goes to A, B, C, and D. Then start by disconnecting (at the junction box) A and B. Then wait a few days and see if problem still happens. If still there, then try disconnecting C. If problem goes away, then check out C, etc. Note: As a rule, these things will work just fine when the electrician shows up!  

My experience at work........ When is sunrise where you live?? A problem the company where I worked had is that when the building outside lights shut off in the morning, it would trip the breaker. These lights were on a sensor to turn on at dusk and off at dawn. We had the breaker replaced, but it kept occuring. We had this sensor replaced on the roof and the problem quit. Maybe the motion sensor has a short circuit tripping the breaker. Is the light sealed properly?? Is the seal between the bulb and the fixture dry and brittle?? Just my $.01

Why is my circuit breaker tripping? 4 common reasons

One of your circuit breakers is tripping? Not again!

How many times do you have to turn it off and on every time you lose electrical power in that particular area of your house?

Circuit breaker tripping may be a common electrical problem in your home that can happen anytime, but how long can you bear its frequency?

If you’re sick of dealing with a randomly tripping circuit breaker, the best thing to do is call an emergency electrician in Melbourne!

Are you experiencing a power interruption? Does it happen when you use your hairdryer, do your laundry, or even when you’re in the middle of watching your favourite series on Netflix?

Then you should do something about your safety switch tripping by giving us a call!

Let an electrician in Melbourne do the checking and testing of your circuit breaker every quarter so you can avoid the hassle of random trips!

Save the number of our emergency electrician: 1300 300 222 – you never know when you’ll need it!

Why is my breaker tripping all of a sudden?

Your circuit breaker protects your entire electrical system from high and excessive electrical currents from a short or overloaded circuit. Breakers usually interrupt the current flow after an electrical fault is detected.

Circuit breakers usually can reset and resume normal operations after being shut down.

What does it mean when your circuit breaker trips?

If you see that your house or a particular area in your home loses electricity, then something is wrong.

You might also experience flickering lights when your circuit breaker trips.

Your circuit breaker should protect your electrical system from electrical shocks and electrical damage due to faulty electrical wirings, overloading and even appliance failure.

So instead of resolving things with DIY effort, find an expert electrician in Melbourne who’s certified and qualified to inspect and fix any electrical issue right away.

What are the signs of a bad breaker?

Your circuit breaker’s job is to protect your entire power system from an excessive electrical load that could lead to electrical shock and electrical damage.

So if you’re wondering if you need to have your circuit breaker replaced or repaired, then here are some red flags that you need to watch out for.

All of which, importantly, negate the expert assistance of an emergency electrician!

1. Circuit overload

Electrical outlets will only have a certain amperage that they can handle.

When there’s a circuit overload, it can cause your electrical connections to stop suddenly.

Power then goes out to your kitchen or living room, which means that your home uses a single circuit to power your home.

When this happens, you need to:

• Go to your electrical panel and turn off your switches
• Reset or unplug your appliances
• Turn on/turn off your circuit breaker

You may need to assess what appliances are causing the sudden power trip by switching on each appliance individually to assess if the item in question is leading to the overloaded circuit.

You may then need to have a local electrician near you update your home wiring system or even add more circuits if needed.

Electricians may need to add a separate circuit to your living room and to your kitchen so that overloading will no longer be a problem.

2. Short circuits

When an electric current veers away from the intended electrical path, a short circuit happens.

There is a low resistance connection between two electrical conductors that supply power to the circuit. When the electricity goes to a different path or suddenly takes a different shortcut to other materials, it can cause a fire and an electric shock if you come into contact with it.

Improper care and attention to short circuits will eventually lead you to experience:

• Excessive heating
• Damage to the power system
• Power tripping
• Power interruption

There are a few reasons why short circuits happen. Some of these may include:

• Faulty electrical wiring
• Loose wire connections
• Faulty appliance wiring

You may need to have your electrical system checked by a certified electrician in Mentone or emergency electrician Richmond to replace your electrical safety switches in Victoria .

3. Faulty safety switch

Poor electrical installation and maintenance can often cause faulty electrical wirings. Such a situation happens if electrical wires have been damaged during a renovation or the electrical wires are old and outdated.

You should also watch out for these red flags of faulty electrical wirings:

• Burning smells
• Buzzing sounds
• Flickering lights
• A blown fuse
• Power points that are warm to the touch

You can have your electrical wirings repaired or completely replaced by an expert electrician in Melbourne at any time.

4. Faulty electrical appliances

Old, damaged, or faulty electrical appliances are some of the most common causes of tripping.

Since some appliances have wear and tear, there may be times that the electrical current leaks, causing imbalances in the electrical circuit. When this happens, your safety switch is triggered to shut off. You need to unplug all of your electrical appliances and turn the safety switch on until the power comes back.

However, if this happens frequently, you will need to contact an emergency electrician in Melbourne to get the best remedy and electrical solution to your emergency electrical problems.

How do you fix a breaker that keeps tripping?

Circuit tripping can happen anytime. Not only is it dangerous, but it can also put you and your family in danger if not fixed immediately.

So here are some things that you can do when you experience a sudden trip:

Turn off all your lights and appliances

If the safety switch does not reset, you need to turn off all your lighting and appliances, especially those areas that may be overlooked.

Reset your circuit breaker

When you have a circuit breaker tripping, you should immediately reset your circuit box.

Safety switches will automatically reset; however, it might be best to call an expert electrician right away if the problem happens frequently.

Test your circuit breaker

Testing your circuit box will give you an idea about the performance of your safety switch.

Doing so will let you know beforehand if there are any problems regarding your safety switch, electrical appliances, outlets or wires.

Call a 24 hour electrician

When in doubt about checking and inspecting your safety switch, it is best to call an expert 24 hour emergency electrician right away to deal with sudden circuit breaker tripping.

Do I need an electrician to replace a circuit breaker?

A licensed Melbourne electrician can do an inspection and maintenance of all your electrical systems, so you have fewer worries when it comes to electrical emergencies!

Circuit breakers are a vital safety feature in any electrical system. Almost any fault will cause the breaker to trip, instantly cutting off the flow of electricity. This action can prevent fires and potentially lethal shocks. While replacing circuit breakers is relatively straightforward in most cases, shoppers might find it challenging to select a reliable, high-quality device appropriate for the situation.

After exploring more than 60 circuit breaker types and sizes and consulting with master electrician Adam Nelson, co-owner of Young Cardinal Electric in Wesley Chapel, Florida, we have the information you need to make a solid decision. This guide also includes a carefully researched list of some of the best circuit breakers for just about every eventuality.

• BEST OVERALL: Square D 20 Amp Single-Pole Circuit Breaker
• BEST BANG FOR THE BUCK: Siemens 20 Amp Single-Pole Circuit Breaker
• BEST DUAL-FUNCTION: Square D 20 Amp Dual-Function Circuit Breaker
• BEST DOUBLE-POLE: Siemens 30 Amp Double-Pole Circuit Breaker
• BEST FOR MARINE USE: Red Wolf 60 Amp Marine Circuit Breaker
• BEST FOR SOLAR SYSTEMS: Chtaixi 63 Amp Isolator for PV Systems
• BEST FOR RV USE: T Tocas 60 Amp Surface Mount Circuit Breaker
• BEST FOR COMMERCIAL USE: Rkurck 30 Amp Push-Button Circuit Breaker
• BEST 50A: Eaton 50A 2-Pole Circuit Breaker
• BEST 100A: Siemens 100 Amp Double-Pole Circuit Breaker

How We Chose the Best Circuit Breakers

Circuit breakers sit inside the main electrical panel , and you shouldn’t need to check them unless there’s a problem, making reliability a key feature for the best circuit breakers on the market. Cheap models that go bad are tremendously frustrating, and—luckily—high-quality circuit breakers are not expensive. All of our picks in this guide are brands that may not be household names but are known and trusted within the industry.

First, we checked building codes and technical requirements to ensure our selections complied with the latest regulations. Next, we wanted to offer as much variety as possible, so in addition to common 20 amp breakers, this guide includes high-capacity options and circuit breakers for RV and marine use.

Nelson echoes the advice of many: “DIYers need to ensure they know the amperage rating on the circuit breaker. If you install a higher amperage breaker, you run the risk of drawing a higher amperage than the wire is rated for—leading to the potential safety risks.” 

Nelson also warns of another potential hazard: “Don’t make the mistake of upping to a higher amperage circuit breaker in scenarios where the circuit breaker is tripping constantly.” A common fault is an overload when a user plugs too many appliances into the same outlet. Upping the breaker amps to prevent tripping can lead to devices burning out and a potential fire.

We have not included smart circuit breakers in this guide. While they do allow monitoring of individual circuits, they are comparatively expensive. There are also concerns about Wi-Fi security and whether breakers might malfunction if the Wi-Fi goes down.

Our Top Picks

These top picks feature a comprehensive range of the best circuit breakers for residential, commercial, RV, and marine installations. 

Product Specs 

• Current rating: 20 amp (A)

• Voltage: 120/240 volt (V)

• Interrupting capacity: 10 kiloamp (kA) (10,000A)

With so many different circuit breaker types and a host of potential uses, choosing a single best circuit breaker is a challenge. However, while our research revealed that many older homes have 15 amp breakers, a 20A model is the most common circuit breaker in use today. We awarded the Square D circuit breaker our top pick because of the manufacturer’s reputation for reliable, durable equipment at affordable prices.

This is a single-pole breaker that takes one slot in the breaker box—also called a service panel or load center. In the home, you will most commonly use this breaker on lighting circuits and standard power outlets. It is also for use in Combination Service Entrance Devices (CSEDs) found inside or outside apartments or commercial premises. Square D is keen to stress its environmental practices, and users can recycle this 20A circuit breaker without special requirements.

Get the Square D 20A circuit breaker at Amazon or The Home Depot .

• Voltage: 120V

• Interrupting capacity: 10kA
• A reliable, durable device from a leading brand at a very competitive price

• Easy plug-in mounting with Insta-wire connectors for rapid installation

• For use in both single-phase and 3-phase service panels
• Complaints are rare, but a few buyers note receiving used devices

The Siemens 20A circuit breaker is a direct competitor to the abovementioned Square D model, and—like the Square D—comes from a brand with an excellent reputation for product quality. The performance and usage of these two products are very similar, including the same high levels of protection against short circuits and overloads. However, Siemens does not recommend its breaker for 240V circuits, although it is safe for use for both single- and three-phase installations in home and commercial service panels.

Like the Square D model, this Siemens 20A breaker is very competitively priced, and the Square D breaker may even be cheaper, depending on the retailer. Ultimately, both products are excellent, so the choice will probably come down to load center compatibility. This is an important consideration as they are not interchangeable.

Get the Siemens 20A circuit breaker at Amazon , Lowe’s , or The Home Depot .

• Current rating: 20A
• Offers the arc-fault circuit interrupter (AFCI) and ground-fault circuit interrupter (GFCI) protection demanded by the National Electrical Code (NEC)

• Plug-in or plug-on simplified connection for faster, easier installation

• For use in household breaker boxes, plus residential and commercial CSEDs
• Considerably more expensive than standard breakers
• Can be prone to unexpected tripping

To understand the value of a dual-function breaker, we need to provide a brief explanation of AFCI and GFCI protection.

NEC now demands that owners of all new homes are installing circuit breakers with AFCI. Slightly confusingly, Square D uses the acronym CAFI (for Combined Arc Fault Interrupters), but it’s the same concept. Arc faults are high-power discharges that can cause fires, so AFCI breakers are intended to prevent these disasters from happening.

GFCIs are ground-fault circuit interrupters. Faulty wiring or equipment can cause a ground fault, which can be particularly lethal if moisture is present. GFCIs are often fitted in bathroom circuits or in sockets where garden equipment is plugged in. While GFCIs are not currently a legal requirement, they are an important safety device.

The Square D 20A dual-function circuit breaker is essentially the same product as our top pick but with these additional features. Along with use in new builds, this circuit breaker can function as a replacement that increases household safety.

Photovoltaic systems (PV) gather DC from solar panels. An inverter then converts the DC to alternating current (AC) for use in the home. There is the same potential for overload and short-circuit on the DC end as any other electrical system, except DC offers the potential for an additional hazard. In the event of the breaker tripping, an arc (spark) can jump across the contacts as they open, which could cause component damage or even a fire.

While standard AC electrical breakers can’t handle this arc, the Chtaixi DC circuit breaker can. It uses a thermal-magnetic trip to perform what is called “arc extinguishing,” thus safely discharging the charge. Visually, this model looks much like many other double-pole circuit breakers, although the Chtaixi is not for use on AC systems.

What to consider when choosing a circuit breaker.

Oil capacity and rating are the primary considerations when choosing the best circuit breakers. Capacity and rating are somewhat interchangeable, which can lead to confusion. It’s important to understand the impact that amps and volts will have on your choice, which we explain in detail below.

It’s worth noting that electric events like lightning strikes can bypass circuit breakers, and thus have the potential to cause serious damage. Read more about how to protect against this occurrence in our guide on whole-house surge protectors .

Capacity usually refers to amps, and specifically the number of amps that can flow through the circuit breaker before it trips. For example, the outlets in a bedroom will usually be 15A or 20A since users typically operate only low-powered electrical devices in that location. In a kitchen or laundry room, the outlets might be 20A for a mixer or a coffee maker and 30A for an oven. Several outlets can be linked to the same breaker, but some outlets—like for an oven or HVAC—will usually have a dedicated breaker.

Capacity can also refer to Interrupt Capacity, which can also be called Ampere Interrupting Capacity (AIC) or Maximum Interrupting Capacity (MIC). This is the maximum amps the circuit breaker can handle without failing. Above this limit, it could short out or weld closed because of the heat generated. For household breakers, this limit is usually 10,000A. As most home electric supply is under 400A, the level of protection is considerably higher than you would ever need.

Amp capacity is sometimes called amp rating or amperage rating. More often, the term refers to voltage (volts). Residential and small business installations usually use low-voltage circuit breakers. Most are capable of handling around 600V. As household circuits rarely exceed 240V, these are perfectly safe. Low-voltage breakers are usually rated as 120V only (sometimes 110V) or as both 120V and 240V (possibly 110V and 220V).

Medium-voltage circuit breakers are used in apartment blocks, large commercial premises, and factories. These breakers may be capable of handling up to 72,000V. High-voltage circuit breakers are usually power line devices and can handle up to 800,000V.

Frequency and Other Considerations

Frequency is given in Hertz (Hz) and describes the number of times the AC fluctuates per second. In complex commercial installations, frequency can be an important factor; however, household frequency is always 50Hz or 60Hz, and the associated circuit breakers are set accordingly.

Compatibility is another key issue, as not all manufacturers’ circuit breakers fit other manufacturers’ breaker boxes. Sometimes this is due to physical size, and sometimes it’s just how they fit. Some breakers clip to a rail, whereas others need to be screwed in. You’ll also find that some circuit breakers have a reset switch while others have a push button. In theory, resetting a push button is slightly faster than a circuit breaker switch. However, the difference is minimal, and as the type generally depends on the kind of installation, there is seldom any choice.

FAQs   

In this guide, we’ve taken an in-depth look at how circuit breakers work and identified which features to consider when choosing the best circuit breaker for a particular application. While it will certainly have answered many questions, a few common queries that we haven’t addressed are answered here.

Generally speaking, circuit breakers will provide many years of trouble-free service, but they can go bad. Outlets that get hot or make a crackling sound may indicate a breaker fault. A circuit breaker tracer could help locate the problem, but there may be other causes. The safest course is to call a qualified electrician to identify and resolve the problem.

Circuit breakers will trip repeatedly if there is a short circuit or ground fault. It will also happen in overload situations when an electrical device draws more current than the circuit breaker can handle. Again, call a professional to identify and resolve the issue.

Install a circuit breaker panel in a location that is relatively easy to access because you want to reset a breaker quickly if it trips. Utility rooms, garages, and basements are popular spots. Don’t install a circuit breaker panel in a closet or any other location that houses flammable materials like paper or clothing.
