Does anyone have a hot tub?







Someone near me is selling a hot tub and I was wondering what maintenance is involved. my dad says I will need to get a plumber to put pipes and such underground. I think i can just trow it on the lawn, fill it, plug it in and turn it on. who is right?
thank you guys very much, how would one generally move the hot tub? if i got a 20 dollar home depot truck, could men surrounding it pick it up, im guessing not.



Answer
First of all, does it work? if you don't know for sure, don't buy it. Hot tub repairs can get expensive.
Most hot tubs don't require underground piping, they just get filled with a hose and are drained onto the ground, or siphoned with a hose.
Most hot tubs require a flat, level base to sit on. Without it, any wood touching the ground will rot. And if the tub isn't given adequate support, cracks will develop. Cracks are very difficult ($$) to fix.
Wiring must be GFCI protected, otherwise you're putting everyone in jeopardy. Even it' a tiny tub with a "Cord and Plug" and a built-in gfci breaker, back it up by plugging it in to a GFCI protected outlet.
Most hot tubs require a 30 amp 220-volt power supply, without it, it takes a loong time to heat up.
The wiring has to be done by a "qualified" electrician.

Routine maintenance isn't too involved or expensive. Replace the filter periodically, clean out stray leaves, check and adjust the Ph level with relatively inexpensive testers and chemicals.
If it doesn't come with a cover, you'll want to get one.
If you don't always have two people to remove and install the cover, you might want to purchase a "spa cover opening system". It's just a metal tubing frame which attaches to the cover and the tub frame and makes it easy for "one-person" removal and replacement.

Wire gauge required for 240v hot tub?




Kosh


The control unit I have needs to be on at least 40-50A circuit (I would imagine it would be best to make the circuit capable of 60A).

What gauge wire do I need for a 60A circuit @ 240V where the run is around 75'-80' from the breaker box?

Also, information on wiring a 240v circuit into the box would be helpful (i.e. links to diagrams and tip sites).

There's a lot of conflicting information out there so I'm looking for some experienced opinions.

Of course, any links to sites where I can learn more about this would be appreciated.
Thanks for the good posts thus far.

One quick question - if I have a 60A circuit, it's made of 30A on each side, correct? So is 6ga required on both sides? Just want to double check.

I'm considering having a pro do the hook-ups but I at least wish to run the wire, conduit and new box to save on that end of it. Maybe I could get someone to cut a deal just to do the concections given this economy.
Irv, not sure what you mean about the "separate 6a bare ground". Do you mean from the panel to the ground? Or a separate run all the way from the tub?
I am not 100% sure I will hire an electrician. Although I very well may. It may take some time to find someone to work at a reasonable price but whom I can trust.

The reason for the inquiry about the wiring is that I will be doing some work in the attic so I'd like to run the line when it's convenient and get that part out of the way.

So I assume I will be safe using a 6ga wire with 3 conductors plus ground? Would I need anything else?



Answer
6 Gage copper, how many wires do you need, have you looked at the unit, it may be straight 240 volts so would be 2 number 6 copper wire with a suitable ground, if it was in my house I would pipe it up and over and drag a number 8 for an equipment grounding conductor.
Sounds like you should talk to an electrician and make sure before you spend time pulling wires you don't need, this will have to be fed with a GFCI breaker and have a disconnecting means some where around the hot tub.
You would be better off getting an electrician as there may be more issues around where you want to put this at to make it safe and if you find a good electrician he will take care of those so no one gets hurt, look in the code book some time you will be surprised at all the stuff that is in there that most people never think about when they do things like this..
the 60 amp breaker is a 60 amp breaker, a 30 amp breaker is a 30 amp breaker.
