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?? Yoopersup
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?? Name plate says Sweetwater Palermo 230 VAC 3-wire connection (60HZ). Yoopersup
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.
