I'tll be a time saver, the short circ calc will need to be done. the distance from the serving transformer constitutes an R factor that seems to play a make or break figure in this calc ( the Short cir. cal).

The end calc is good for only one point, and as you stated L-L, or whatever. To complicate this would be to introduce the concept of "series" rating, or whatever could happen L-L, or otherwise down through the components.

I suppose i'm just confusing the issue here...
