I have been in HVAC-R service work for a long time, but not a lot of installs. I'm installing a spa for a friend, 50 amp main panel breaker, a 50 amp "Swan brand" GFCI panel by the spa. I've run 3 # 8's, 2 hot and a neutral,and a # 10 ground. The run is under 50 ft. Could you tell me if this ground is big enough, and do I need to drive a ground rod to land at the ground strip in the spa box.Main panel to spa panel is PVC, and spa panel to spa is mettallic sealtite.This is probably the best web site of any subject I have interest in, glad it's here. Any help is appreciated. thanks, bassbug

Re: Hot tub on a deck

Not to be rude, but here in Reno any run over 10 feet must be done by an electrician.

A ground rod is worthless at the tub. The ground wire must be run all the way to the panel that feeds the circuit. For those outside the trade, play it "simple, safe" by using the same size wire as your conductors. Use PVC underground, and metal above ground.

Re: Hot tub on a deck

Rigid nonmetallic conduit is perfectly legal according to 352.10 to run exposed and in some cases if installed properly (strapped with listed straps and expansion joints where necessary,check table 352.44[A] and {B}} can make for a more economical and better quality installation than metal. I have seen a lot of exposed emt that looks in bad shape over years of weather.

Re: Hot tub on a deck

Ren- thanks! I repulled a #8 for ground. I wasn't sure so - ask the experts! Everything is O.K., spa works well,GFCI is operational, etc. You were not being rude, but here in upstate N.Y. you do not need to be licensenced, and in 40+ years of HVAC-R work I can say I have never had a problem with any jobs I have done, which I cannot say of the countless (licensced,qualified) electricians I have had to follow and redo their work. Nuff said!- I don't like to argue. Just glad that rescources such as this are available.
