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.

anyone know anything about safe hot tub temps?
idk
I work at a hotel in the state of Illinois and we have a hot tub and need to know what the health code says about the lowest and highest temps can be in our hot tub.
Answer
There are no low temp regulations. The Feds put a limit of 104 for the highest temp allowed for a hot tub. Major medical problems start at 105. There's also a time limit of twenty minutes for all new tubs at 104. Of course Fed regulations override your states. They are going to be more worried about the sanitation you are keeping in your tub. 3-5 ppm Bromine or 1.5-3 ppm free chlorine.
