Just looked at a large parts washer at one of the industrial facilities we work at that they want to install. The existing service is 480/277v The machine draws 280 Amps at 230 volts according to the name plate. I need to put a transformer in for the 208/120v loads in the area already. My question is, is there some way to avoid having to put in two separate xfrmrs? I am thinking I can't get a buck boost that big. It seems the only solution is to install a xfrmr to service the 208 and , and another one for the equipment. Am I missing something? :?
