I’m not an electrician.

I used to have a Scuba shop and had the compressor located approximately 100’ from the panel box. The compressor motor was 5hp 220v single phase and the electrician used 10-3 wiring.

I know this is the reverse of what you asked but the motor/compressor ran fine with this size wire. My logic is that 10 gauge wire can carry a fair amount of current with little loss over a distance of 100’. With 200’ you will probably require a larger gauge.

I’m not an electrician either.

If it’s the 17kw generator that I found specs on then it’s a 65 amp service. By using this calculator: http://www.csgnetwork.com/wiresizecalc.html with a 200’ run 65 amps on aluminum wire you’d use #1 wire.

Where’s Topamax when you need him?

I would spend the extra and go with copper. I have never trusted aluminum.

Have your say...
