How To Replace a Circuit Breaker

A circuit breaker is a safety device that is used in an electrical circuit. The purpose of the circuit breaker is to prevent damage to the electrical circuit when there is an overload in the system or if there is a short circuit. It prevents damage by stopping the flow of electricity when it detects that there is an error. Circuit breakers are common in many homes.

If you need to replace your circuit breaker, you need to follow certain steps so that you can do it safely and successfully. If you are not too confident of replacing the circuit breaker by yourself, it is advisable to call an electrician so that you can avoid accidents from happening.

Here are the steps on how you can replace your circuit breaker:

  1. Purchase a circuit breaker. The first thing that you have to do is to buy a replacement for your circuit breaker. Be sure that you buy the correct size of circuit breaker. To be sure, bring your old circuit breaker so that you can get the exact same type. There are different types of circuit breakers that are sold in hardware stores. Some of them are the MCB or Miniature Circuit Breakers, the MCCB or the Molded Case Circuit Breaker and the low voltage power circuit breaker. These are low voltage circuit breakers that are mostly used in residences.
  2. Turn off the electricity. As with any task to do with electricity, it is imperative that the power to the home is turned off before you replace the circuit breaker. 
  3. Familiarize yourself. Open the breaker panel to expose the contents inside. You will see two wires that are connected to the circuit breaker. Before you remove the wires from their position, remember where they are connected as you will have to reconnect them later on.
  4. Removing wires. The next thing you will have to do is to remove the white wire. To do this, you will have to use a screwdriver so that you can loosen the screw holding the wire in place. You do not have to remove the screw all the way. You just have to loosen it enough to remove the wire. Once you have removed the white wire, you can loosen the second wire. After this, you can already remove the old circuit breaker.
  5. Install the new breaker. Install the new circuit breaker in place. Reconnect the wires that you removed from the old circuit breaker. Connect the white one first and connect the colored wire after the white wire. Use the screwdriver to tighten the screws just enough to keep the wires in place. Turn the breaker switches on if needed. When everything is secure, you can replace panel of the circuit breaker.
  6. Turn the electricity back on and you're good to go!

These are the steps on how you can replace your circuit breaker by yourself. You have to follow instructions carefully to make sure that you install the circuit breaker the correct way. The circuit breaker that you buy might come with instructions on how to install it. The installation of a circuit breaker is pretty much the same but it would be better if you follow the instructions that came with the circuit breaker that you bought.
