tjb32 Posted September 7, 2013 Report Share Posted September 7, 2013 Got a used 2100 cal spa, read the specs as 220v, 40 amp so we installed a 40 amp disconnect (10 feet) then to a 40 amp GSI breaker in the breaker box (60 feet). Ran all the wire (6 gauge aluminum from the breaker box to the disconnect, with an extra ground wire), then copper from the disconnect to the spa. As soon as we turn on the GSI breaker it immediately trips. Then we read where it needs a 50 amp GSI. My question: Would a 40 amp GSI always trip when meant for a 50 amp? Then we realize we should have put the GSI at the disconnect and not so far away. Would running the GSI that far always trip right away?

arches2 Posted September 9, 2013 Report Share Posted September 9, 2013 if it's tripping immediately and won't stay on at all you most likely have it wired wrong assuming that there was no ground fault in it when you bought it. Did you see it operating? If the circuit was overloaded it would stay on at least for a couple seconds. You have a GF somewhere. Quote Link to comment Share on other sites More sharing options...
Dr. Spa Posted September 9, 2013 Report Share Posted September 9, 2013 The neutral wire(s) is probably hooked to the GFCI breaker incorrectly. Quote Link to comment Share on other sites More sharing options...
tjb32 Posted September 9, 2013 Author Report Share Posted September 9, 2013 I did see it working before. As a test we unhooked from the wires from the spa, made sure they weren't touching, & flipped the GFC on. At that point it did not trip.

tjb32 Posted September 11, 2013 Author Report Share Posted September 11, 2013 Yes, you guys were right, it was a neutral wiring issue at the GFCI, it was connected to the panel and not back to the GFCI itself. Thanks for all your help Quote Link to comment Share on other sites More sharing options...
