I recently had GFCI breakers installed for my filter, waterfall, and booster pumps as the original were non-GFCI. I also replaced my old incandescent lights with 12v LED that are on a separate GFCI breaker. When the bonding wire is attached to either pump, the breaker trips immediately. The electrician double checked everything but can't find a cause so for now, I'm leaving pumps off when swimming. The breakers are Square D and the filter pump is about 6 yrs old. I understand the purpose of the bonding but since the only metals parts in the pool are the niches and now have the LEDs, do I still need it? Thoughts/suggestions? Thank you in advance!
