Already have the 30amp box, and yes it will be in conduit. Was hoping to get by with #8 but after reading the link it looks like #6 is what I'll need to go with. Probably will never be 50amp but who knows?? Wish I could put in a shop there but the village won't let me put sides on the shelter, only floor and roof. Oh the fun of living in a town with zoning. Takes some getting used to. Just moved here from large acreage in the country with no zoning or rule-do what you want. But we're really downsizing to where we can leave for long periods of time. A tradeoff I guess.
