Advice on GFCI Breaker to Pool Panel Timer and Pump. I'm feeling it's a bonding issue. House Panel to Sub Panel in garage. Neutral & ground separate in Sub Panel. Sub Panel feeding Pool Panel ( Intermatic T3000R with Time clock ). Neutral & ground separate. 20amp/120 volt GFCI Breaker feeds Time clock which then feeds twist-lock receptacle to pump. GFCI instantly trips. Pool pump motor double insulated plastic. No bonding lug. In past, we bonded to Lug on T-11 box holding our Twist-Loc. Does Pool Panel have to be bonded? Problem #2. Time clock motor is 208/240. Is there a way this can be used? :? Already tried these few things: By passed time clock motor. GFCI Holds and pump runs fine. Also tried, 20amp/120 volt time clock. Same result. GFCI trips instantly. Is it possible I'm picking up leakage thru the Pool Panel. Thanking anyone in advance. Anyone??? :blink:
