How to Install a New Circuit Breaker? Know Before Installation

What is an electrical breaker?

The electrical circuit breaker is a safety device that is used to safe electrical device from short-circuits current or over voltage. However, the circuit breaker is a protective device used to open the circuit whenever an undesired fault occurs. It is used to close the circuit under healthy conditions. The circuit breaker can operate manually or automatically if necessary. It can also be controlled by remote. In most cases, the electrical circuit breaker works automatically (make or break the circuit without human interference). However, in this section, we will talk about the low-voltage (220 or 440 volts) circuit breaker installation process. So, take a look at how to install a new circuit breaker panel, wire a new outlet to the breaker box, and many more.

How to install a new circuit breaker and outlet?

The circuit breaker is a crucial device that is used to safe home equipment. Make sure you have connected your essential equipment to the breaker before installation. But how to install a new circuit breaker into your electrical panel let’s try to figure it out step by step.   

  • Decide the place where you want to install the circuit breaker
  • You must turn off the main breaker before installation
  • Remove the panel box cover
  • Install the circuit breaker in the panel box
  • Connect the installed breaker in the panel
  • Test the breaker after completing the installation 

Decide the place where you want to install the circuit breaker

First of all, decide the place where you feel safe and make sure that your power distribution board is not far away from your load. You should remember that you should place your breaker board in any location where there is no chance to be short circuit. So, find such a location and install your breaker box.

You must turn off the main breaker before installation

Remember, before installing a circuit breaker you must keep off your main power supply. If you would like to install a single breaker then you must disconnect the power supply for safety. The circuit breaker is likely to have more current value. However, you should make sure that your installing breaker is in the off position. Why do you need to do that? It is because you must make sure of the proper safety before installing any devices.

Remove the panel box cover

We again make sure that before removing the panel box cover or work you must off the main breaker or disconnect the supply line. Now remove the panel box by using a screwdriver but you should follow caution. If you shut off the main breaker it not means there is no power in the breaker box. That’s why test the power by using an electrical power tester or you can use a digital multimeter or volt meter to measure the voltage. If you get zero volts after testing then you can be sure that there is no power at the breaker box.

Install the circuit breaker in the panel box

How to install a new circuit in an electrical panel box? Indeed the breaker should be installed in the electrical service panel or breaker box. This breaker box is mainly located near the main electrical service entrance and houses the circuit breakers that control the electrical circuits in your home or building. Keep your breaker off position place the breaker and align it with other breakers. Basically, there is a stripe with the breaker that makes it easy to installing a new breaker in the main panel. So don’t worry about setting up the breaker.

Connect the installed breaker in the panel

After installing a new circuit in an electrical panel, you can connect the breaker to your load but make sure that your breaker is still in the off position. Basically, you should connect the neutral wire and hot wire to the breaker. Remember, if you install the double pole circuit breaker then you have to connect to both black and red hot wires. In this case, you have to remember that you are using the switch that was designed to be used as a double pole circuit breaker.  

Test the breaker after completing the installation 

After installing a new breaker properly, clean some other waste or foreign objects and press on the main breaker that you were kept off position. After making on the main supply make on your newly installed circuit breaker. If you see that your breaker is okay and the load is getting power properly then you can be confirmed that installing a new circuit breaker has been perfect. Now you can cover your breaker box as per your previous. So, it is a simple process to install a circuit breaker. 

How to wire a new circuit breaker?

If you would like to wire new circuit breaker to connecting a new circuit breaker to the circuit breaker panel then you have to off the main circuit breaker. Basically, the breaker panel has two lines (live wire and neutral. You should follow some steps to wire a new breaker, such as

  • First of all, shut off the main breaker.
  • Now take off the breaker box.
  • Take a wire new outlet to breaker box and measure how much wire you need for the line and neutral connection.
  • Now connect the breaker live line and neutral
  • Now power ON the main breaker and check the new breaker
  • If everything is better then cover the breaker panel.

What circuit breaker do I need?

It is a funny question which circuit breaker do you need to know well about it? If you require a low-voltage circuit breaker then select a low-voltage breaker based on your load capacity. On the other hand, if you require a high-voltage circuit breaker then choose the best circuit breaker based on your load capacity. However, there are some factors that you should know about what circuit breaker you need.

  • Electrical Service Panel: Identify the type and size of your electrical service panel. This will determine the type of circuit breaker you need (e.g. standard, miniature, etc.).
  • Amperage: Determine the amperage of the circuit you are working on. This will determine the size of the circuit breaker you need.
  • Voltage: Determine the voltage of the circuit you are working on. This will determine the type of circuit breaker you need.
  • Application: Determine the type of application (residential, commercial, and industrial). This will determine the type of circuit breaker you need.

What does a breaker do?

The circuit breaker is used to provide better safety for low-voltage and high-voltage crucial devices. We know that a breaker is an electrical safety device that automatically disconnects a circuit in case of an overload or short circuit, preventing damage to the electrical system and reducing the risk of fire. Circuit breaker works by detecting an excessive amount of current flow through the circuit and tripping the circuit breaker, interrupting the flow of electricity.

What causes a circuit breaker to go bad?

Yes, the circuit breaker can go bad due to some common reasons that we know. However, let’s see what cause can make a bad breaker.

  • Overloading: when a circuit breaker is tripped too many times, it can cause internal damage and weaken the breaker.
  • Age: over time, circuit breakers can wear out and become less effective.
  • Electrical surge: high voltage spikes from lightning strikes or power surges can damage a circuit breaker.
  • Mechanical failure: the moving parts inside a circuit breaker can become worn or damaged, leading to failure.
  • Corrosion: exposure to moisture or corrosive substances can cause damage to the internal components of a circuit breaker.
  • Manufacturing defect: in rare cases, circuit breakers can be defective from the factory and fail shortly after installation.

Final thought

A breaker is a well-known and common protective device. That is used to restrain to flow of the short circuit current into the appliances. However, we have shown above how to install a new circuit breaker panel, and we have also shown above that how to add new circuit to panel. We hope you got the better idea to install a new circuit breaker into the circuit breaker panel. So, stay with openread and get innovative things.
