I have a circuit protected by a GFI circuit breaker that has failed. So far,
I eliminated anything plugged in or switched. Also determined that the

this way for now.

Its impossible to check the actual wire runs behind the sheetrock. Is there
anything else to check as a possible source of the trouble?

Is it possible there is another GFI on the same line? Like a GFI
protected outlet? My old shop had 2 GFI outlets on a single 120
circuit plus a GFI breaker on the 220 volt hot tub circuit. If I
tripped any of the three, all were tripped! Very frustrating until I
discovered the need to reset all of them when one tripped.

Good luck,
