Question

480 voltage to 200 amps


If someone can help me. I have a business and have been told 10 different things by different electricians. I have 100 amp service comming into my building with 480 volts and then running through a 480 3 phase transformer.
Does that mean or is it possible to turn that 100 amps into 200 amps? Thanks if you can give me any info.

480 voltage to 200 amps


480v x 100 amps x 1.73 = 83,040 VA.

83,040 VA / 208v / 1.73 = 230.76 amps at 208/120v 3 phase


I am assuming a 3 phase system, stepped down from 480 3 ph to 208/120 3 ph.
