How to Test a GFCI
There are 2 buttons on a GFCI, a RESET button and a TEST button. Before the first use, press the RESET button. Plug a device into the receptacle, such as a radio or lamp, and turn the device on. If it works, everything is if fine. If the device does not work, press the RESET button to see if the problem is corrected. If power is still not available, check the main circuit breaker, and then inspect the wiring for a possible short before the receptacle.
