Hi all..just had my wiring done for my tub that is arriving tomorrow. I know NOTHING about electrical and some numbers seem odd to me in my setup so was wondering if all is ok. Was done by an electrician, but wanted to just double check for my own piece of mind. Spa is a Coyote Drifter, according to the manual, can be wired with "32A single circuit, two 16A circuits or three 16A circuits (3 phase). So, in my main breaker box, the breaker used for the spa is one of those double breakers...each of the two smaller breakers of the double breaker is labeled "40". I take it this is 40A...so if there are two of them, is that 80A total? Or just 40A for the whole double breaker? I would hope it is 40A, since my tub needs 32A...and I guess is 40A is the closest to 32A, so that's why it is used?? I take it there are no 32A, or 35A breakers? Second, my GFCI is 50A (provided by the spa dealer)....again, is this ok at 50A when the spa is only 40A? Thanks for any help, I'm quite the moron when it comes to electrical. Have a structural engineering degree, and the only course I EVER failed was in 1st year of the generic engineering courses...yup, it was Intro to Electrical Engineering!!! ops:" title="Embarassed" />

Since no one else has replied I'll give it a shot from a Civil Engineers perspective. The tub draws 240 VAC at 32 Amps max. You need to have at least a 32 Amp breaker and GFCI to provide adequate current to the tub without blowing. Since breakers don't come in 32 AMPs they sized the next size up. 40 Amps works. Same for the GFCI. Bear in mind the breakers are essentially there to protect against a severe overload and to act as traffic cop to prevent you from drawing more juice thru the wires than they can handle. The GFCI is there to ensure the appliance circuit is properly grounded. SInce all this was done by an electrician I would assume it is ok. Obviously CE Structurals worry far too much " title="Wink" />.
