What happens here
Plug the Klein Tools GFCI outlet tester into the newly installed outlet. The tester will illuminate and display '120 VAC CORRECT', confirming proper voltage and correct wiring of the hot, neutral, and ground. Press the 'TEST' button on the tester to simulate a ground fault. This action should trip the GFCI outlet or the upstream GFCI breaker, causing the tester's display to go dark or indicate a fault. This confirms the GFCI protection is functional. Restore power by resetting the GFCI or the breaker.
Goal: Verify correct outlet wiring and functional GFCI protection
