Need to size a 240v 10kw generator wire. It'll be carrying 42 amps. Looked in section 28 and they don't have much for sizing the generator wire. Do you have to times it by 125% like a motor? so 42 x 1.25= 52.5 A. so a #6 copper or #4 AL... if someone could help me out with a rule # that would be great. Thanks.
