I have a 150kva 480v single phase primary with 240/120v single phase secondary xfmr. It is intended to feed (2) 400A 240/120v MCB panelboards with #600kcmil to each. The neutral is bonded in the transformer and a 3/0 is used. If a ground wire is installed in the conduit from the transformer to each panelboard, is it sized per T250.66? Or is it sized per T250.122?
so is the feeder supposed to be 3#600kcmil, 1#3/0G ?
or is the feeder supposed to be 3#600kcmil, 1#3G ?
Or is it something else all together?
Thanks
