I already have a 70a sub panel left over from a prior job. I have the grounding rod, weatherheads, pvc, just need to know what type of wire. That said, I agree with you guys, that if I can't figure out the wire needed, then I most likely lack the knowledge to be even messing with this stuff. The wire will leave my big barn pretty high so I'm not real worried about clearance, and it's just going over my yard. An extension cord would solve a lot of my problems, especially since the wife wants the basement bath done.
