We've recently bought some used 480v/3 ph machine tools and a fork battery charger and will soon power them up. Here's the diagram on the transformer that we'll feed backwards and get our 480 from the primary. We take 208v. 3 ph from a 100 amp breaker in the main breaker box, the transformer is the only load on that breaker.
I want to make sure I'm interpreting the 7 transformer terminals correctly. I think X0 is where I connect ground both from the panel and to my loads, is that correct? I got that impression just due to the process of elimination, that's the only terminal that's not obviously one of the hots for each phase. I'd like verification that X0 is where ground wires go.
Panel breaker to transformer is via 2 gauge stranded copper, ground wire is no. 6 stranded copper. Transformer output to loads is 4-wire, 8 gauge, goes to the fused disconnect panel here.
Our initial loads plugged into the outlets shown will be a large forklift battery charger and a 2 hp pedestal grinder which we don't need to run simultaneously.
I have no experience with 480v. And I noticed on the transformer diagram what appears to be delta primary and wye secondary. I know power to motors is normally from a delta circuit. Am I keeping my wyes and deltas in their proper places with the way I'm hooking this up?
