    3 Phase Feeder Size
    I am having a 3 phase 208 volt electric system installed in my wood shop. A 320 amp meter base is installed feeding 2 200 amp 3 phase panels. There is some question as to the size of the main feeders and the neutral wire size. I think I want copper installed but was told aluminum may be less cost. Thank you
