That is a 120v 15 amp receptacle. I hope you have a neutral feed to the pool or a transformer that is creating the 120v. If this has been installed in the last 20 years, it should have a proper neutral and should be safe to use. If it is an older system that had an added 120v circuit, then there may be some safety risks because the neutral for the light ...

My pool runs off a double 15A breaker (240v), which includes the pump and pressurized pool cleaner (a Polaris). Salt pools use a powered chlorinator to generate chlorine and chlorinators change things a great deal. Some use less than 15A and are on a standard 120v plug. Some are direct wire and need as much as 30A and 240v. Pools can also have lighting, but ...

Most electricians doing this work for themselves would actually do one of two things. For the full 100A, use #1 aluminum. You may have heard negative things about aluminum (you'...

Using copper THWN #4 is only good for 85A, which is not a standard size breaker. So you could if allowed by AHJ to upgrade to the next standard size, 90A. #8 copper ground is good for 100A. 3@#3 and 1@#8 would barely fit in 1" Sch40 PVC, you would need 1.25 for Sch80. A 6 space MLO panel would work, but risky that some future change would require more ...
