A plug and play hot tub. It runs on one 110V but is capable

Customer Question

I'm Installing a plug and play hot tub. It runs on one 110V but is capable of converting to 220V, which is what I'm wanting to do because it turns a 1 kW heater into a 4 kW heater and will operate more efficiently. It It has a pump that is 1.5 horsepower. The main electrical panel is approximately 50' away. What size circuit breaker should I use? I am aware that it needs to be a GFI breaker as well.

Hello my name is ***** ***** evening. Is this an indoor or outdoor spa? Does it come with a remote panel and wiring? Or what does it have for connections?

Customer: replied 7 months ago.
It's an indoor/outdoor 2 person tub. We are using it outside. It came with a 180" cord plug in cord for a 110v wall socket. I've already spoken with the spa manufacturer about how to wire for 220v. I just had to remove a jumper wire and the cord that came with it. I am going to hardwire it. There is a terminal for line 1, line 2, neutral and ground. I need to know what size breaker so I can pull the appropriate size wire

Ok. Well you would probably want to go with a 30amp breaker and 3 conductor #10 wire, red/black/white and a ground. So you would have to install a standard 2 pole 30a breaker in your main panel, and feed a spa panel minimum 5 feet away and in sight of the spa. Inside the spa panel will be your 2 pole gfci breaker which will feed the spa. Also out of that panel you will need a 120v gfci outlet that is 10-20 feet away.

That is exactly what I did already! I just wasn't sure if 30 amp was enough and I keep hearing different answers. The only thing I didn't do was the 120v gfci outlet out of the same box. There is another outlet within 10', will that do or does it have to come from the same circuit as the spa? What is the reason for it? Sump pump?
Expert:  Steven Parent replied 7 months ago.

Oh ok perfect then. The 120v outlet does not need to come out of that spa panel, sometimes it is just handy. Your outside plug may already be gfci protected, if not, just change it. Basically a convenience plug i think, for maintenance, radio or lights or whatever.

You said your spa is 4kw, so 4000Watts divide by 220 volt = 18.2amps. A 30 amp feed gets the job done.
