If you're wondering how to install a Square D GFCI (ground fault circuit interrupter) circuit breaker, you have come to the right place. Installing a GFCI circuit breaker is a great way to keep your home safe and up to code.
A GFCI circuit breaker is designed to shut off the power whenever it detects a current imbalance in the wiring, which can be the result of a malfunctioning appliance, a short circuit, or even an animal chewing through the wiring. Without a GFCI, these types of problems can cause serious electrical fires.
The first step in installing a GFCI circuit breaker is to make sure you have the right one for your specific application. It's important to do a little research and make sure that the size of the breaker is appropriate for the amperage rating of your electrical system. You will also need a set of wire cutters, a flathead screwdriver, and a voltage tester.
Once you've selected the proper GFCI breaker, locate the main panel box and turn off the power. This is the most important step, as working on an electrical system with the power still on can be very dangerous. With the power off, remove the cover of the panel box and find the area where the GFCI breaker will be installed.
Next, loosen the screws on the terminal of the breaker and connect the grounding wire. Then, attach the hot wire to the other terminal and tighten the screw. Make sure not to overtighten the screws to avoid damaging the wire. Next, attach the neutral wire to the neutral bus bar and tighten the screws. Lastly, attach the ground wire to the grounding lug in the panel box, then replace the cover.
Before you turn the power back on, be sure to test the breaker with a voltage tester to make sure that it is wired properly and is functioning correctly. Once you are certain everything is in order, turn the power back on, and you're all set!
