I haven't hooked up a Hot Tub in years. Someone asked me if a 240 volt Hot Tube requires 2 hots, insulated neutral & a Ground. He said by reading instructions it only requires 2 Hots & Ground ??? Since a White , Blk, Red come out I was sure be 2 Hots , Neutral & Ground .. Any out there hooked one up lately??

Cut to the chase, and run all four wires all the way to the tub.

While it's possible to get a '240 only' tub, most these days actually have you feed to a control panel under the tub. From there 120 circuits branch off to feed controls, lights, TV set, etc.

Better to run it and not need it - for now.

Usually the feed to HOT TUBE is seperated feeder then branch circuits to outlets, lights ect

You are required to have another receptacle anyway.

I have seen hot tubs go either way, all 240 or 120/240. I do agree with Reno, run all 4, just so you have some flexibility later. It may just be an add on feature you want.
The usual GFCI I see is 50a 120/240 rated with a neutral pigtail.

I looked at the wireing diagram it shows 3 wires YET says it has 120 volt controls. I feel 4 wires also but Listing & labeling of manufactor says 3.interesting hey.
Also I know outlets required just doesn;t come off feeder to hot tub controls under HW.
The HT does have GFI with neutral also.

Anyone else run into this??

Hmmmm.....

I would look really good at the wiring diagram. 120 volt controls, perhaps a control xfr within the tub control panel?

Whatever, I would run 2 hots, 1 neutral, 1 ground. All that I have seen around here are 4 wire units. 50 amp & the occasionall 70 amp.

Youpersup, if you're saying that thse other things around the tub are usually / should be on separate circuits, I agree.

I suggest you visit a tub showroom, though. You would be simply stunned at what comes 'built in' to some of the upscale models. The last one I installed had all the bells and whistles - even the built-in TV set!

I have run into several of these tubs that had marked 240v 3 wire that were in fact 120/240. One customer had a 240v ckt with ground, the tub was 120/240, told the customer he needed a new ckt. He called the tub manuf. the guy on the phone told me to just hook the white and green together. I walked away from that job because I would not do it.
