Hello, I'm thoroughly confused by three phase right now and am working on a homework for my power class.
Is 480/277 always WYE? The 480 refers to phase to phase voltage, where as the 277 refers to phase to neutral, correct?
So if I have a 480/277 4 wire setup, then it has to be wye?
If it is wye, or if it is delta - what would be my line current if I had say a 10kW load?
I'm just confused by the notation since there is no Y in the middle (480Y277) Is that all there is to it?
Sorry if this is a dumb question, but I thought there was some sort of standard on this notation until I came across this.
