Sub panel wire size chart.

A 100 A sub-panel requires a two-pole 100 A breaker - if you want 100 A. You can use #4 AWG 75 deg C or 90 Deg C copper wire in conduit for a 100 A breaker provided the breaker is labeled for use with 75 deg C wire. A #8 copper ground is adequate for a 100 A feeder If running NM cable or SE cable, you would need #2 copper, I believe.

You can use the same gauge for the hot, neutral, and ground wires. The ground wire is a defensive component that directs the current to the earth when a malfunction occurs. You can also use a larger ground wire than all the other wires because it has less resistance.

2 Answers. YES you can use #4 Al as your ground. Your 1AWG Al is good for a 100 AMP feeder (actually 110). From NEC 250.122 this requires an #8 CU or #6 Al ground wire as a minimum (or 6CU and 4 Al if you are really running a 110Amp Feeder). As a reminder, your feeder will be 4 wires, the two hots and the neutral will be #1AL (unless you've de ...
