A guy called because he's haaving trouble with his outdoor hot tub. It's four years old. Evidently had some internal problems that were repaired by dealer. Now his 60A 2 pole GFCI trips, even with no load connected to the lugs. Dealer tells owner that cable is incorrect from panel to disconnect - no neutral. Cable is 6/2 w/#10 or 12 bare ground.
The white wire from the GFCI is not connected.
I've looked at some older posts on this board and have concluded that a neutral is not required to be run if there is not a need for one. I think the white wire from the GFCI should be connected to the ground bar in the outdoor disconnect box. Would the fact that the white wire is not connected cause the GFCI to trip with no load connected?
I'm going to read art. 680 this evening but right now I feel owner may have a bad GFCI and no neutral is required. Anyone?
