Alright, here's my dilema.
I am opening a new wood shop and have three phase at the panel. It is 277/480 from the road to the panel. From the panel it goes into a transformer that breaks that up into 208/120. My american made machinery is multi-tap 208/230/460 which is not the problem. My european/pacific rim machinery is multi-tap 220/440. I would like to use 208v as I realize it falls within the +/- 10% rule. However, would it be preferable to use 480? It would run "cooler" but falls within 8 volts of the 10% rule. If I use 220v it has 10 volts to spare. I am a little worried that in the hot, summer months the voltage drop would be enough to let the smoke out of my equipment!
Ideas?
