wep1981 Posted July 19, 2017 Report Share Posted July 19, 2017 Hello everyone. I've been browsing the boards for a while now. We were handed a Caldera Tahitian Utopia hot tub from the wife's co-worker. I had a spa moving company deliver the hot tub but they left the sub panel. I have a question about wiring the sub panel. I need one 20 amp and one 30 amp GFCI breakers. Do I need double pole breakers or can get away using singe pole? I'm thinking of buying the materials from homedepot and assembling instead of purchasing the whole Caldera Sub panel for $400. The plan of action is to purchase 50 amp breaker for main panel, run 6/3 romex with ground through the house to the sub panel then 2 thhn #12 from 20 amp breaker to hot tub and 3 thhn #10 from 30 amp to hot tub all in PVC. Plus Run one #10 insulated ground from sub to hot tub. I'm also a little confused about this statement from the electrical installation part: "Always ensure the white neutral wire is connected to the load neutral of the 30 amp breaker. " What does this mean? Quote Link to comment Share on other sites More sharing options...
Dnepr Dave Posted July 19, 2017 Report Share Posted July 19, 2017 I bought a used Caldera Kauai that came without the sub panel. I was able to buy the correct sub panel and breakers from a local electrician who specializes in hot tubs for $200. I didn't want to wire it differently than designed. Will your wife's co-worker let you have the Watkins dual breaker box? Quote Link to comment Share on other sites More sharing options...
Dan.The.Spa.Man Posted July 19, 2017 Report Share Posted July 19, 2017 You need a double pole 30 and double pole 20. On the 30 amp gfci breaker there will be a seperate terminal for the neutral wire in addition to the two hot wires. Quote Link to comment Share on other sites More sharing options...
wep1981 Posted July 20, 2017 Author Report Share Posted July 20, 2017 Thanks for the replies. I will look around for electricians. I also want to test out the tub before buying everything. I have a Champion Generator that has 240 Volt AC, 30 Amp, single phase 60 Hz electrical loads. Can I run a plug from the generator to the hot tub and connect to the board for testing?

Hot Spring Official Posted July 20, 2017 Report Share Posted July 20, 2017 Unfortunately you aren't going to have enough amperage from the generator to operate the spa. Quote Link to comment Share on other sites More sharing options...
