Depends on the length of the run
Randall, the length of the run is going to determine the size of the cable you are going to need to run. First, you want to size to have a no more than a 3% voltage drop over the length of the cable. So with that in mind here are the recommended sizeUp to 3 1/2' 4 AWG3 1/2-6' 2 AWG6- 7 1/2 1 AWG7 1/2 - 9 1/2 0 AWG9 1/2 - 12 00 AWG12 - 15' 000 AWG15 - 19 0000 AWGIf you have any more questions please feel free to e - mail me.Good luckCharlie
