1. How to Test a GFCI Outlet
- Find the test and reset buttons.
- Press the TEST button.
- The outlet should trip with a "snap" sound.
2. Confirm the Power is Out
- Plug in a lamp or other device.
- The item you plug in should not turn on.
3. Reset the Outlet
- Once you confirm the GFCI is working properly (that the outlet does NOT work when tested), press the reset button to restore power to the outlet.
4. Retest for Remaining Socket(s)
- You can also buy a GFCI outlet tester with a display and test button.
GFCI protection can also be installed on circuit breakers to safeguard an entire circuit. Test monthly by pressing the test button on the breaker. If working properly, the interrupter should shut off power to the circuit.
