Wow, that's far (see above post #3). You can google electrical voltage drop to get a better understanding of what you are up against.
A few examples of the maximum distance using #10 wire while maintaing a voltage drop of 3% or less.
A maximum distance of 343.076 feet will limit the voltage drop to 3% or less with a #10 Copper conductor delivering 5.0 amps on a 120 volt system.
A maximum distance of 171.538 feet will limit the voltage drop to 3% or less with a #10 Copper conductor delivering 10.0 amps on a 120 volt system
