One of the GFCI circuits in my house keeps tripping. It's installed in a bathroom outlet, but it also supplies a couple of outdoor outlets downstream.
I replaced the GFCI unit over the weekend, but when the house painters arrived today it tripped again.
I had them use a different outlet in the garage, and that seems to work fine. I don't think its their equipment, as they weren't working over the weekend when we experienced the earlier problem.
Is there a recommended way to identify/test the outlets and the wiring in between them?
I'm not at home at the moment, but I expect that there's been a build up of corrosion, etc in one or both of the outdoor sockets.
Some tools I have available include: Fluke 289 and an insulation tester(250 - 1KV)
