To be sure your life-protecting GFCIs are working properly, use this test or the instructions that come with the GFCI.
- Plug a night light (or radio turned up loud, if you have a circuit breaker GFCI) into a GFCI-protected wall outlet, and turn it on.
- Press the GFCI test button or switch. The light or radio should go off.
- Press the reset feature to restore power.
If the light or radio does not go off when the test button or switch is pressed, the GFCI is not working or is not wired correctly. Contact a qualified electrician to correct the problem or install a new GFCI.
