Wire sizes



Here is a basic guide to Wiring sizes to use for Power and Ground cables. There are obviously higher rated cables when you look into professional wiring kits and the cables themselves can handle higher current draw, but this is just a basic guide to keeping it safe.

2/0 AWG - 400 amps

0 AWG- 325 amps

1 AWG - 250 amps

2 AWG - 200 amps

4 AWG - 125 amps

6 AWG - 80 amps

8 AWG - 50 amps

10 AWG - 30 amps

12 AWG - 20 amps

14 AWG - 15 amps

16 AWG - 7.5 amps

Please check the fuse rating on your amp or look in your user manual for your amp to see what the current draw will be. If you are running multiple amps, make sure that the cable to your distribution block from the battery is able to handle it.
