I have a dead outlet that I can't quite figure out. It's a GFCI outlet about 10 feet from the breaker panel (in the same room). It is (as far as I know) the only outlet that is dead in the house.
Several non-contact voltage testers, a plug-in tester, and a volt meter have confirmed that there is no voltage at the plug. I have a circuit tracer that sends an audible tone up the wire to find the breaker, but it requires an energized circuit to work.
Is there a good way to trace this circuit in the current condition? I'm hoping to not open the wall any more than necessary.
