Now we have to test the GFI before we are complete.

  • Turn power to the circuit back on at the service panel.
  • Make sure the RESET button found on the front of the GFI is pushed in and not the TEST button (the TEST button will shut the GFI off).
  • With a neon circuit tester test for power at the GFI.
  • Replace the cover plate. There should also be a little sticker with the GFI that says "No Ground" or something similar. Place that on the GFI to alert people that this outlet is not grounded.
You have now greatly improved the safety of this electrical outlet by installing the GFI. Even though it is not a grounded outlet, the GFI will protect against shocks.
