I just ran some uf-b wire for 2 lights 10 foot from the pool. As I read code these do not need a gfcb but I am putting one on it. I wired it up to a regular breaker this weekend to make sure it worked and it did. Covered the trench and it worked fine. After 3 days of rain today I went to connect it to a gfcb and it trips instantly. It just wired it to the pool light gfcb as it does not draw a while lot of amps and I need the other slots. It does not trip when the perimeter lights are not connected. Is there anyway to tell what is causing it to trip? Also it is wired to a relay in the aqua logic. Just hope I am not gonna have to dig all this wire back up as it is about 80 feet.
