30 Amp Wire Size: Charts, Gauge, Breakers (120,240 & 480 V)
According to the National Electric Code or NEC, the correct wire size for 30 amps is 8 to 10 AWG wire. But it will vary based on the wire material, distance, and voltage. You can also use a lower gauge, but 10 AWG is the minimum, and 8 AWG is the maximum.
