My Hot Tub GFI keeps tripping. The first thing I want to do is determine whether the problem is: 1) the hot tub or 2) the wiring to the hot tub. I want to do a simple test where I disconnect the wiring at the hot tub. I would go to the main lugs in the hot tub and remove the wires which are fed from the breaker and have them connected to nothing. If I do that and the GFI does not trip, have I correctly determined whether the problem IS the hot tub? I have read lots of posts about going to the control panel in the hot tub and disconnecting various components of the hot tub (heater, pumps etc). But I want to disconnect the hot tub completely (at the hot tub, not at the breaker) and see if the problem is the hot tub or the way that the hot tub is wired to the breaker. Will this work? Thanks very much.
