What is typical for a hot tub prewire?

[arazu]

My client has no idea what make/model they are going to purchase. Without specs I'm unsure. The company I used to work for would pull 8-2 but that seems low to me.

I was hoping someone who works with hot tubs a lot could offer some advice.

Thanks!

The size of the heater and the pump are a function of the size of the tub. Check with these guys; they have everything:

it will most likely be less than 50A 240v
w/o knowing the specs, i would pull NM-8/3 or if conduit 8-8-8-10(gnd)

Beware: Many installation manuals require a "full sized ground" (same gauge as line conductors) as well as only copper conductors.

I'd also estimate 50 amps or less. But, I think you meant 6-3 NM since 8-3 NM is only rated for 40 amps.

Without specs, I wouldn't do anything less than four No. 6s. The price generally tends to help them make a firm decision.

I think you're right about the price helping them decide.

I had no idea some required a full size ground. I was hoping to use 6/3.

Thanks to everyone who responded. You've been a great help.
