May 26, 2023 · The minimum wire size for a 100 amp sub panel is 4 AWG copper or 2 AWG aluminum. It is based on the 83% rule, which defines that the wire size should handle 83% of the amperage of the sub-panel. In these conditions, 83% of 100 amps is 83 amps, so the wire size can handle at least 83 amps. I agree with Greg you can put in any size sub panel. Other than the panel size having to be the same or larger than the feeder breaker, the limiting factor is the wire size feeding the panel that is what sets the feeder breaker you can feed a 100 amp panel from a 10awg wire with a 30 amp breaker. I have done just this.Correction:. I meant to say #8 for the ground. Thanks all, I will go with #3 for neutral and #8 for my ground. In most cases the grounding electrode conductors (ground wires to ground rods etc.) are #6 copper to direct buried or driven rods and #4 copper to water pipe or concrete encased rods.1. At 125’ 4 awg copper would provide 1.79% voltage drop using 4 gauge wire would allow for 70 amp breaker in your main panel. Since this is detached you will want a ground rod also. To save on wire cost you could use #2 aluminum and still have 70a breaker at the main. If you would like to play with wire sizes google southwire voltage drop ...
