We have a 225kva transformer, with 480v primary and 208 sec. The installation the way it is now, has 2 - 4" seal tights, each going to a 400amp switch. Are you allowed 2 diffrent disconnects on the secondary side? Do the secondary conductors have to terminate into a single switch or breaker? Such as a 600 amp main breaker panel? Can they end up into 2 switches?
Thanks
