Yeah,40a overload/fault @ the panel and GFI @ the disco,good idea, is it kosher? Just got back from the h/o's;the co. he's getting it from has a 40a GFI x-t disco for $100 so I told him to get it; I wasn't finding one local.BTW,he called hot-to-go, but when I got there some concrete guy was taking his measurements: I chuckled.And thanks.
