Ground fault circuit interrupters (GFCIs) are an important electrical safety feature. A GFCI outlet contains a sensor that monitors the amount of power going to an electrical appliance. If there is an interruption in current the GFCI cuts the power, potentially saving a life. These monitors are especially critical in bathrooms, kitchens and anywhere else water is present in the environment.

Because GFCIs can fail without notice, it’s important to check them monthly. Pick a day you will remember, such as the first or last day of the month, so you are sure to maintain a regular schedule.

Follow these instructions to safely test your GFCIs.

Shut off power before you test; to confirm the shutoff:

  • Plug in a lamp or other device

  • The item you plug in should not turn on
