lat week I was at a customer house to repair the Wiring on there hot tub. Hot tub was manufacture in 1992.
The original installation was made using EMT laid directly on the ground and no GFI breaker.
I installed new PVC and a GFI breaker re pulled in 4# thhn Copper conductors. nameplate calls for a 40A circuit max.
The home owner called me to day to say that when the heater is turned on the GFI trips immediately.
I amped out the Neutral and ground wire together and am reading 8.22 MA . the hot tub runs fine with out the heater.
any idea on what is causing the Heater to trip.
