Today I came home to find out that my GFCI breaker tripped sometime between last night and this morning. We had a rain storm, but nothing near like we've already had, so my thought is its not moisture.

Anytime I plug my pump into the GFCI circuit, the breaker instantly trips. If I leave a receptacle on the circuit, even without anything plugged into it, the breaker *eventually* trips (minutes, hours later, etc.) Currently have bare wires (covered of course) outside with the breaker on waiting to see if the breaker trips all by itself.

Any ideas? I know a couple people recently had issues liek this, would be interested to see what fixed it....and also anyone that may have had something liek this happen (this actually happened to me 2 seasons ago, I thought it was fixed because it worked fine all last year and so far 2 months this year).

Thanks in advance.
