I want to use this in our facility but we only have 208 3 phase. Short of having a major change to our facility power, I thought of this. I want to get a small step-up transformer (about 9KVA) and wire it to plug in to one of our 208 3 phase 30 Amp receptacles.Crossboss. IMHO the ideal transformer for this job is a 208V delta to 480/277V wye step up transformer. Probably 45 or 75 kVA. The current at 208V must be greater than the current at 480V, so you are correct, 100A at 208V is the equivalent of of about 43A at 480V.Wiring diagrams, sometimes called "main" or "construc-tion" diagrams, show the actual connection points for the wires to the components and terminals of the controller.
