Well, on a SQ D slide-rule my teacher gave us last semester, it states that a 75 KVA can hold a maximum of 208A at 208V, 180A at 240V, 90A at 480V, and 72A at 600V.
Then, going from 310.15, 4/0 for 208V, 3/0 for 240V, #3 for 480V, and #4 for 600V.
I barely finished my 1-year program, I'm barely going to start my Apprenticeship. Someone correct me if I'm wrong.
