Its been over a year since I've sized conductors according to the NEC, so I'd love some help.
I have 2 legs of a 480/277Y feeding a 100A CB, which feeds a 25kVA step down 480V-120V transformer for a panelboard. I'm not sure how to correctly size the conductors on the secondary of the transformer. Could somebody walk me through that? On the primary side, I have 2-#3's for my current carrying conductor and 1-#8 for my ground conductor. Correct?
Thanks!
