Had a service call today no power to the pool house. The control panel is protected by a GE 50A DBL pole GFCI breaker. This panel has 7 circuits in it all related to the pool area. First thing I did was replace the main breaker. Problem is still there. Out of the seven different circuits only the one controlling the pro logic will not trip that main GFCI breaker. This is an existing pool area and has worked fine for years. I tried isolating the circuit with the ground fault in it but no luck. Can anyone give me some trouble shooting tips? Thanks

Disconnect the branch circuit wiring from the pool panel breakers. Turn on all the breakers, see if any trip the main. If they don't, then the problem is with the branch circuit wiring. Check ohms on each branch circuit (hot to neutral, hot to ground, neutral to ground), verify no shorts. No shorts means a ground fault trip. Suspect the circuit with the lowest ohms first and work toward the highest ohms. Reconnect them and turn them on individually, see which causes a trip. Trace the wiring on that one/those. Eliminate the ground fault.

I never liked the idea nor have I ever used a GFCI breaker as the main for a pool panel. Any little fault and the whole panel goes down. I would use a regular breaker for the main then use GFCI branch breakers where needed/required. It might be a little more expensive on the owner but they will thank you down the road. You will also find a fault a lot quicker as you will know which circuit has the fault.
As for now, do as Copper man says and disconnect all the wiring and put it back one circuit at a time until you find which circuit has the fault. When you find the circuit, disconnect the equipment on that circuit and see if the fault clears. If there is more than one piece of equipment, try them one at a time to isolate the problem.

We're all suspecting that the problem is a ground fault problem. If what Coppersmith described doesn't work, try leaving the wiring on the breakers and disconnect all the ground wires on the ground bar. Start with all the breakers in the off position, then turn on one breaker at a time and see if it holds. Assuming it does, try landing one ground wire at a time back on the ground bar starting with the feed. It could be a motor that developed a ground fault.
