hottub

[dchajz]

I,m installing a hot tub that requires a double pole GFCI breaker at a subpanel.Is a neutral wire needed or required from the main panel to have the DP-GFCI work properly?No 120v circuits will be run from this subpanel.The hot tub has no 120v loads.

Re: hottub

i have a friend who has a hot tub that requires 240 volts for the heater and 120 volts for the pump and control wiring. he is telling me he needs a two pole gfic circuit breaker with a neutral monitoring tap! my supply house doesn't know what i'm talking about. is there such a thing??

Re: hottub

From the main panel to the "spa panel" you will need 4 wires. 2 hots, 1 grounded (neutral) and one EGC.
From the breaker to the spa you will need three or four. Some spa mfgrs. require 4 wire hook-ups, and others only three (no 120v loads) That will be determined by the spa's listing and the manufacturers instructions.

edit: Charlie is too fast for me.
Charlie, I don't know what you're after either. I hooked up a bunch of spas, but never had anything like that come up. What brand is it?
Everything that we ever sold was 3 or 4 wire. We only used 2 pole GFCIs

Charlie,

I think this is an example of what you're looking for:

this one was recalled several years ago btw:

Re: hottub

thanks bill,
do you think this is available in square d ? or are you saying they don't make them anymore? this is an older tub and it originally had a gfic in the tub's control section --then someone removed it and from what i understand it was then operated from a gfic protected outlet. and the guy ran the entire tub on 120 volts. but it took for ever to heat up. now he wants to change it over to 240 volts --- the instruction manual has a drawing for each voltage. but as soon as he turns the unit on the 2 pole gfic(square d) trips since it is sensing a difference between phase current. i believe the problem is the fact that the internal gfic was removed... maybe it will require the 2-pole gfic to feed the heater and a separate single pole gfic to feed the pump and controls? does this sound correct? hate hot tubs!!!

charlie,

Sure, they're available. The first one I could find a picture of happened to be one involved in a recall, that's all.

Re: hottub

charlie,

I just read the rest of your comments. It sounds like you may have a real headache there. I hate when people start messing with internal wiring, there could be something wrong in there.
