Hello all,
Here's my dilema, I'm upgrading an exisiting building to a machine shop.
Currently it has a 400 Amp 3 phase 480 Main Service.It has a 227 KVA Transformer on a(480 volts) 200 Amp breaker feeding a 400 amp 208/120 three phase secondary panel.
I want to put the transformer (227 KVA) on a 400 breaker(Primary),and go to parallel 3/0 feeders for the primary side.
I want to add an additional 225 Amp panel and feed directly off the secondary taps on the transformer.The new 225 Amp panel would have a 225 Amp main breaker.
I'm thinking this is legal.
The 227KVA transfomer at 208 volts according to my calculations can handle 618 Amps.
Thanks for your help in advance
