I had to run a new underground service to my house. I bought it from my electrical supplier. won`t hurt to go a little oversize, but might make it harder to hook up. you don`t need any convertors for 110. take it off one side of the 220 . A bout 40 yrs ago, I took the power for the outlets off one side, and the power for the lights off the other side of my 220, in my garage. w/ a 50amp breaker, I can weld , run my lathe , or mig welder w/ the lights on, no problem.
