The op is installing a 400 amp service using 2- 200 amp panels. T. 310.15(B)(6) is not allowed-- that is a 400 amp service. By the way I don't believe 2- 200 amp panels are considered a parallel install. To be parallel they must begin and terminate together.It is based on the wire size you use for the hot and neutral connections. For 100 amps, if you use 4 AWG copper or 2 AWG aluminum wires, you can use 8 AWG copper or 6 AWG aluminum wires for grounding. If you follow the ampacity chart, you will need 3 AWG copper or 1 AWG aluminum for 100 amps. In that case, the ground wire will be 8 AWG copper ...May 24, 2023 · So, a 250 kcmil wire is ideal for 200 amp. The size depends on how far you run the wires from the sub-panels to the main panels. The wire has to be at least 2 AWG thick. However, it also depends on the cable length. If you run a wire 200 feet away from the main electrical panel, use a minimum of 1-gauge copper wire.It will have a 200 amp service and they ran 4/0 Aluminum 269' from the transformer that was set 3 years ago when we renovated our house.
