    dumb MechEngr voltage-power question

    A client has received a machine rated at 480Vac 3Ph 60Hz 15KVA max, 3KVA running. They want to install the machine in a temporary location that only has 208Vac 3Ph 60Hz available. I had to reach 'way back behind the cobwebs and vaguely remember the phrase "step-up transformer", but associated...
