What Size Copper Wire For 400 Amp Residential Service. For a 40a circuit breaker, the correct wire size is #8 awg for copper and #6 awg for aluminum. the best wire size for a 400 amp service would be 1,000 kcmil aluminum wire or 600 kcmil copper wire. And for the ground, a 1 awg aluminum wire should. Selecting the appropriate wire size for a circuit is crucial to prevent overheating,. However, the wire to choose for the service panel may differ. (were this not a residential service, you'd have to provide for the full 400a nominal requirement, which'd require another size bump to paralleled. you just check the nec feeder sizing table and see that, for 200 amp service, you will need either a 2/0 awg copper wire or 4/0. We have to use thick kcmil copper and aluminum wires. this wire size calculator will calculate the appropriate wire gauge for a circuit based on amps, voltage, distance, and load. However if you run them. did you mean that the inspector is requiring 600 kcm copper to feed a 400a service?.or 400 kcm copper?. You need 3 awg copper or 1 awg aluminum wire for the ground wire. for a service rated 100 amperes through 400 amperes, the service conductors supplying the entire load associated with a one. for 400 amp service, we can rule out the standard awg wires. according to the nec, the wire size for 200 amp service is a 3/0 awg copper wire or 4/0 awg aluminum wire.
