Somewhat new to the forums, I bought my house about 3 years ago and have had nothing but trouble with my pool. For the past month I've been follow the trouble free pool method and things are looking up. Less trips to the local pool store and no more buying dubious chemical concoctions promising the world and falling way short.
My equipment looks to be hobbled together through the years by the previous owner and I have been doing research for a major upgrade, swcg, variable speed pump, larger filter, automation, maybe even some lighting. The question I have is about my subpanel, currently it is wired for only 110v and is run off a 30 amp breaker at the main. Is it possible to convert the panel to a 220v using the existing wiring? I read somewhere that the neutral can be wired as a second hot from a new dipole breaker? Not sure if this would work as it wouldn't leave a neutral for any 110v devices connecting to the subpanel? I only ask because the subpanel is a considerable distance from the main and copper ain't cheap.
Secondary question - In the experience of the forum, does 30 amps even give me enough headroom for a new system? If it's not enough, I might as well rewire with a lower gauge anyways.
