Can you guys confirm if I sized transformer, primary and secondary circuit breakers correct?
Primary Voltage: 480 volts, 3 Phase
Primary Load: 231.97KVA (279.1 Amps)
Secondary Voltage: 120/208 volts, 3 phase
Seconard Load: (644.36 Amps)
I selected a standard 225KVA transformer.
Primary MCB: 350 Amps
Secondard MCB: 800 Amps
I was told that my circuit breakers sizes are too high and exceeded the transformer capabilities Are my calculations correct? Thanks
