How to replace a circuit breaker is a question most homeowners are faced with at some point. There are two sorts of circuits, and these are open circuit and closed circuit.

The first type consists of electric circuits, and the second type includes gas, water, oil, and other electrical appliances.

In addition, the third type of circuit is the combination of the two, and it contains both the electrical appliances as well as gas and water heaters.


Don’t Wait for How to Replace Bad Circuit Breaker

Usually, a circuit breaker will never have to be replaced unless it has become damaged or shorted out. Unlike a fuse, an electrical circuit breaker is made to the only reset if there is a fault or overload in the system.

Identify Breaker’s Brand & Size

When you see the breaker panel cover plate, you will notice the numbers stamped on them. These numbers will correspond with the circuit breaker you have chosen. These numbers will tell you which circuit to be replaced and what breaker to cover.

Each type of circuit has its own requirements when it comes to the amount of electricity and the strength of the current flow. This is why knowing the number is so important.

Replace Circuit Breaker at Home by Knowing Breaker’s Type

One of the most common mistakes made when replacing a breaker is choosing the wrong breaker for the purpose.

If the breaker is the wrong size, the voltage that you need to have will also be too low, or the breaker will fail to shut off properly.

Once you know the type of breaker you need and how to replace it correctly, you can do the rest easily.

Don’t Forget to Use a Voltmeter Before Proceeding

When you are looking for the correct breaker for your circuit, you should use a voltmeter. A voltmeter will give you a reading on the current and the voltage that is flowing through the circuit that needs to be replaced in order to ensure safety.

The reading of the meter will be read on a scale from one to four.

At the top of the scale is zero volts, and three-quarters of a volt is the maximum allowable to reach a full rating.

The second scale is three-quarters of a volt, and zero volts is the lowest voltage you should ever have to reach to avoid a fire.

Check the Readings Adequately

The third scale is the maximum current and the voltage; you should never have to get near to reach failure for your circuit breaker.

The fourth level of a scale is when you are close to the maximum current, you should go to failure.

Once you have the reading you need, you will be able to replace the circuit in a matter of minutes.

If you do take enough time to read it carefully and use a good instruction manual, it shouldn’t take you more than five of minutes.

Keep Track of the Markings at the Back of Circuit

You will want to remove the circuit breaker from the wall and then look at the markings on the back of the circuit.

In some cases, it remains better to just simply replace the whole circuit rather than the individual breaker parts.

When you are looking at the markings on the back of the circuit, make sure to note the voltage that is displayed and the maximum current that is indicated in the circuit.

Buy an Appropriate Outlet

A decent way to save money is to buy an outlet that has more than one outlet. This will help you be able to handle more circuits that are needed.

The last thing to remember when you are shopping for a breaker is to be careful with the type of circuit you buy.

Lead While Following Best Protection & Performance

There are many of the things that you require to know if you want to know how to replace circuit breakers in your home.

This info will show you how to replace the circuit breaker if the unit is leaking, has been damaged, or is not functioning at its best.

You will also learn what the best wire to use is and how to cut it to the proper length. Also included in this article will be some information on what wire to use for the best protection and performance.


  • When the circuit breaker stops working, it can cause all kinds of problems to your electrical system.
  • These include but aren’t limited to, an increase in voltage, and possible fire. Sometimes, the problem is simple.
  • Overloaded breaker and too long wire run will cause a circuit to break down. Other times, the problem is more complicated.
  • If you have an overload of current coming from an electrical outlet, the circuit breaker may fail, leading to a surge, which can damage wires and even a fuse.
  • A surge is usually caused by water, but can also occur when someone accidentally runs their circuit breaker all the way open.

There are some sorts of circuits that are meant for certain outlets and not others. For example, if the circuit is not meant to handle the outlet, the appliance can overheat and cause a fire. If you aren’t getting sure what you are doing, just leave the breaker open, and you should be fine.
