I just ran uf-b direct burial wire to 2 light poles 10 feet from our pool. They worked fine on a regular breaker. It has rained probably 4 inches the past few days. Now I connected it to a 15amp gfcb ,just for extra protection considering it is so close to water, that only has the pool light on it which pulls 50 watts. Gfcb trips instantly when the 2 pole lights are connected. Does not trip when only pool light is connected. It is connected to a aqua logic sub panel with built in relay timers. Is it possible I already have a problem in the wire? I didn't use conduit except coming out if the concrete where the pole lights are mounted and up to the sub panel. I sealed the light poles with silicone but could moisture have gotten inside the pole? Just want to know what's the 1st logical thing to try 1st to trouble shoot this problem.
