My renters are complaing that the breaker for the master bather and bedroom keeps tripping. They say the trip is random. I tested all the plugs and GFCI plug in the bathroom. Everything passed with my GFCI tester. The house had a unwelcome rat for a few weeks and could have chewed a wire, really hope not.
The only odd thing I can see is the breaker shows 1/4 white on the arch fault indicator.
Could that be the issue?
