Good advice all around. I found an electric supply place that is getting me 50 ft. of 8-2 w/g for $1.26 a ft. which is a nickel less than Home Despot wanted for 10-2 (?!). I've run into this before -- HD seduces one into thinking that their prices are always lower and they're not.

I'm about 60 to 70% of an electrician -- I'm confident I can do this safely. I turn off the main breaker at the panel, of course, doubly important due to the 3 phase power in that box. The 3rd leg has a black cable feeding it with an orange band around it, the digital tester says it's 201 volts. Ouchy.
