Testing The Circuit Breakers At Home

The reason for circuit breakers as an element of your home's electrical system is to provide another layer of safety. Without properly designed and installed circuit breakers, your house could be in danger of overloaded electrical circuits, which might cause serious damage or possibly a fire. Circuit breakers are created to break the flow of an electric current if it exceeds a safe and secure level. It is important to remember that even if your circuit breaker system is undoubtedly properly designed, you need to have it tested periodically to be able to make certain that it works the way that it was created to operate. If you're not informed about electricity, it is advisable to leave this testing to your professional Sacramento or Elk Grove electrician. If you do understand something about electricity and are also comfortable dealing with it, then you may be able to test out your home's circuit breakers on your own. Here are some tips you can use to safely and effectively test this important component of your home's electrical system.

Essential Tools

So that you can properly test your home's circuit breakers, you will need a few basic tools. One item that you'll want to have on hand will be a voltage tester. You can usually find these at the home improvement center. Make sure you buy one that's rated to test up to 500 volts. You also need to have some rubber-soled shoes for safety, some safety goggles to keep your eyes protected, and a screwdriver which you'll use to open the electrical panel.

Safety Issues to Consider

Like all electrical jobs around the house, safety should be your primary consideration. Before you even go near to the circuit breaker panel, you have to put on your rubber-soled shoes as well as your safety goggles. You should also be sure that the floor surface beneath the panel that you are going to be standing is dry and free from obstacles that can allow you to trip and fall. If you are unfamiliar with how you can properly make use of the voltage tester, make sure that you have an electrician teach you the way you use it. As with every tool, improper use of the voltage tester could result in a tragic accident. When you're using the voltage tester, it is important that you never touch any exposed bare wires and the neutral wires.

How you can Perform the Circuit Breaker Test

After you have donned your goggles and rubber-soled shoes, you may use the screwdriver to very carefully open the circuit breaker panel. Now, using your voltage tester, use one prong of your tester to touch the circuit breaker terminal screw. Next, use the other prong to touch the ground screw. Take care not to come in contact with other wiring within the panel. If the test has been properly performed, the lighting on the voltage tester should turn on, which indicates that this breaker is working properly. When the voltage tester light doesn't turn on during the test, it's an indication that your circuit breaker isn't functional. If you discover this to be true, then you need to replace the circuit breaker that's malfunctioning. More often than not it's the best idea to leave replacing a circuit breaker to your licensed Sacramento electrical contractors.
