Good afternoon Wizards, (there are some really smart people here!)

I have wired up my 1 hp water pump with #12-2 wire w/ground on 220 volts right at 400 feet. It registers the correct voltage and amperage at the pump. According to the wiring chart that came with the pump, I think I'm at the maximum length of this size wire to have the correct volts/amps. My question is I want to extend the wire another 200 feet to hook up to my other house's electric panel. Can I add 200 feet of #10 or #8 wire and expect to get 220v and 8 amps to operate the pump? I don't want to discard the entire #12 wire (already buried) unless I absolutely have to.

Thanks in advance for your advice!

Sincerely,

Don L

The short answer is , give it a try. If you end up with too much voltage drop, then replace the 12/2 with larger cable.
