Hot tub wiring
So I am getting a hot tub and wonder how tough it is to get 220 wired for it.

Gas is not really on my wish list.

Has anyone done this in a DIY format?

I have a separate junction box for the garage with the adequate space for the power, just need to figure out how to get the power to the tub.

its not to bad, i hate doing elec stuff and just google searching i managed to come up with enough knowledge to hook up the welders, the hot tub, the sump pump and all of that stuff. by far the most unpleasant part is getting the wiring through the house, I have a ranch style home so i have full access end to end through the basement and attic. I hope your that lucky as a more complicated floorplan to turn that into a nightmare!

I replaced the heater and control box in ours last year myself and had to switch from a 3 wire to 4 wire 220. But, I ended up paying an electrician to do the new wire run between the control and main house fuse panel because I was freaked out about lots of electricity controlling a big tub of water. :o It was simple though, and I think the wire ended up costing more than the electrician. I thought it was worth it to have the expert do it and he ended up finding a ground issue I would have otherwise missed.

easy. shut off the main power supply, run the wires, hook em up, turn power on. just have to know what size wire to run. i just finished running a 50a circuit for the welder/plasma since the only 220 outlet that i had was in the far corner of the garage.

if you need 6/3 romex, i can make you a deal on about 18' ;)

Chris when I had mine installed you need a 50 amp breaker that is at least 10 feet from tub on outside of house. I don't know if code has changed, but you may need a permit and inspection. Dan

Thanks Dan and all that have chimed in..

Chris, its not really any harder than 110 once you understand the wiring principles of 220. Just check your local codes for placement and distance from your hot tub (water source) and do it. If in doubt use the next heaver gauge wire for any given distance. And I would place an outside breaker near the tub whether code calls for it or not. Just easier in the long run.

Thanks Corbet!

Here is what I got today.. It was tough choosing this over maybe a 40 but I really have wanted one of these for post skiing days forever..


I think I did ok on price. 6400.00 includes Uncle Sam's take, delivery, cover, cover lift, chemicals, seats 6, 36 inches high..

Sundance uses a UV water cleaning light, so chemicals are minimal.

Got it from Spa Palace in Westminster off of Wads and 101st, Ryan is the sales guy. Really nice guy. Today was the last day of some truck sale...;)

The PO department is wondering why this did not go through the proper approval process and is having a hard time accepting this as worthy of emergency purchase status...

Now just make sure you put it under the zip line :lmao:

I just cracked open my copy of the NEC (National Electrical Code) Book and checked into hot tub and spa requirements. I should hope you would have known intuitively that everything needs to run through GFIs (Ground Fault Interrupters). Also, all wiring needs to be in conduit, and there are specific burial requirements. The spa and hot tub subsection is about 3 pages, the entire section (which also covers swimming pools and fountains) is about 21 pages.

I would bet a 6-pack that a hot tub install would require pulling a permit and passing inspection in most municipalities.

I would be comfortable doing this myself if I were interested in having a hot tub. It isn't rocket science, but there are very specific requirements.
