Ok thanks everyone. I'm heading to Lowes in a few and its #6 copper and a 50A breaker. By the way I used to go on a lot of Storm Damage teams after Hurricanes and such. A lot of people do the backfeed thing right or wrong. When we got to a neighborhood to start restoring power the first thing we did was ride around listening for generators and when we found one we would pull the meter on that house so they couldn't backfeed onto the grid. Then we grounded on both sides of our work and if we missed a generator it wasn't going to last long.

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." C.S. Lewis
