Your load could be (maginally) handled by a #10 wire in terms of not
overheating the wire and insulation. So that means you need to size the
wire for voltage drop. A quick calc (assuming 2 wire circuit) says that
#10 copper will give you slightly over 10% voltage drop out at the well
head, #8 gives 6% drop, #6 would give you 4% drop. If this is an

wire - 27.5 amps, black wire - 19.1 amps, yellow wire 10.8 amps. I

I assume you're talking the red wire. How does a #6 red, #8 black, and
#10 yellow compute? I need to order Monday morning.

This is just a V=IR problem. Anybody know where to find R per 100' on
different wire sizes?
