outdoor hot tub

[banshman]

Hello, newbie here. Im trying to gather wiring for my outdoor spa.Iknow I need 6 gauge wire. I was gonna get 6-3 from home depot to run from my 220 service to a junction box where the wire will go outside. This is where im confused. I believe I need an insulated ground outside which forces me to get 4 seperate wires to go from tub to GFCI box then to the junction box mentioned above. I wanted to get the underground cable and just nail to the underside of my deck to get to the tub but it doesnt have an insulated ground. I cant bury in conduit because the deck is only a foot off the ground but I can get in there to nail to joists. Im so confused, any help would be great.



thanks

What i would do is use liquid tight conduit and run individual conductors through that. This can be hung underneth your deck.

What size breaker does your spa require?

Check your data plate or installation instructions. Some spas can be run on a 3 wire system but that is if they are 220v only. Most spas require a 4 wire system (2 hots, 1 neutral and a ground). That is because some of the equipment is run on 110v such as the blower, light or possibly the pump depending on HP and the heater will probably be 220v.

Thanks for the reply eveyone. My sister gave me this hot tub. It is a 4 wire setup with a 50amp breaker.The junction box will be under a 3 season porch. Thats where I believe I have to switch to an outside setup.
