100 amp sub panel ground wire size.

For a 100 amp sub panel that is 200 ft from the main, it is recommended to use 4 AWG copper wire or 2 AWG aluminum wire. These larger sizes of wire can carry more electricity and reduce the amount of voltage drop on the circuit. Additionally, they are strong enough to handle longer distances and still provide enough current for the breaker.If we have to run single phase 120V circuits or 2-poles 240V GFCI breaker, we will connect the white neutral wire from the main service panel to the subpanel box. Click image to enlarge. Keep in mind that #3/0 gauge wires should be used for 200A breaker and #1/0 gauge wire for 150A circuit breaker (NEC 2017 - Table 310.15 (B) (16) & 310.15 (B ...Updated on February 15, 2024. According to the NEC, the wire size for 200 amp service is a 3/0 AWG copper wire or 4/0 AWG aluminum wire.
