This is a voltage drop question. To answer this question a voltage must be stated.
4 gauge
18 amps.
12 AWG. You can run several hundred feet.
8 gauge will be sufficient with less than a half volt drop
This is a voltage drop question. To answer this question an amperage is needed.
The duration of As Far as My Feet Will Carry Me is 2.63 hours.
#10 wire is good for 30amps; however it is wise and sometimes required to use an 80% load factor. If you need 30amps continuously you would want to use #8 wire, which is good for 40amps. #8 wire could safely run 32amps continuously, 40amps x 80% = 32amps.
A #10 copper conductor with an insulation factor of 90 degrees C with a 3% voltage drop is rated at 30 amps
