A ground fault circuit interrupter (GFCI) is a device that protects people from electrical shock. It does this by interrupting the flow of electricity when it detects a ground fault. A ground fault is a situation where electricity is escaping from a wire and flowing into the ground. To ensure GFCIs are functioning correctly, they should be tested regularly.
Testing a GFCI is a simple process that can be done in a few minutes. First, press the “test” button on the GFCI. This will cause the GFCI to trip, which means that it is working properly. Next, press the “reset” button to turn the GFCI back on.
