I have a pool with a sub panel that has a 30amp breaker for the pump, a 20 amp for the lights that is also connected to a small fridge receptacle, the water heater has two 20amps on it. The main breaker for the subpanel is a 60 amp gfci. This breaker keeps tripping. Any suggestions?
Can you post a photo of the breaker panel configuration? I'm deeply suspicious that what you're seeing might be due to damage to the GFCI breaker itself...– ThreePhaseEelNov 15, 2017 at 2:10
How old is the pump?– Paul LoganNov 15, 2017 at 2:16
4Your going to have to divide and conquer. My opinion is you likely have a ground fault. Turn off individual breakers until it doesn't trip.– TysonNov 15, 2017 at 2:20
1Tyson this should be an answer. It is the only way to figure this out without equipment to measure the current imbalance.– Ed BealNov 15, 2017 at 3:09
Im with Tyson on this one also. I suppose you could also have a short somewhere, or if anything is touching water it will trip a GFCI real fast.
Probably is a GF, but it could also be a combination of the heater on full blast, the lights on, the fridge running and then the pump comes on. The inrush of the pump starting while everything else is already running may be too much for that 60A breaker.
