hot tub

[Pierre C Belarge]

I would install it the way the tub manufacturer states even though I think it is BS that they put in those requirements. Pie seems to be the only way to go.

As George stated NM is rated 60c not 75C. you will find this in art. 334.80

Actually NM is rated at 90C, but is fused at no greater than the 60C column.

Celtic will agree with that.

:grin::grin::grin:I fixed it thanks

after i posted i looked at the book and saw 334.80.Thanks.
But why do you think they would require the EGC be the same size as the ungrounded and grounded conductor? At this load (40 amp per manufacture name plate) it doesn't make sense to me? Maybe i'm missing something.
Besides #10 EGC would be sufficient per 250.120 table.

You are correct. Boy, you have to be exact around here.:grin:

Personally I think the manufacturer doesn't know why other then their legal dept is covering their butts. I wish they would prohibit the manufacturer from doing this esp. in this case.
Another case is hydromassage tubs where some installations require a #8 back to the panel-- another bs requirement, IMO

I can vouch for that as well. I have been corrected on this site 1,865,654,209,812 times.

i ran into the same thing with a spa in garage. had two outlets , one on wall(GFCI) and one for door opener.shoved tub back in coner(after ripping out the shevling unit). Then GFCI garage door outlet, was not required to bond trac for door opener. Owner didnt like it, but passed inspection.

That would exclude the use of NM altogether. So in these situations you run the circuit in conduit?

I'd run 8/3 or 6/3 Rx to the subpanel/disconnect. From there I'd give them their #8 EGC to the tub.

Here in AZ we're allowed to run NM for the circuit with an additional/separate #8 THHN green wire from the bonding lug on the tub pump back to the panel

Don't forget they will need a minimum 20cfm continuous exhaust fan installed in the garage that will discharge directly to the outside now that the hot tub is installed

Where did you get that information?

It seems sometimes we forget the NEC is not the only codes we have to adhear to, we have the fire, mechanical, and a group of sub codes including local and State code additions, Some states also have rehap codes, so you need to stay current in all the related areas.

Nope, you missed one. That makes 1,865,654,209,814 times.
