Bj,
You'll have to forgive me for saying 45 KVA. I should have said 50 KVA. It's a 3 phase world out there, and I'm used to living in it (thus 45, 75, 112.5, etc). The Project Specifications call for 500 amps @ 240 volts. The big question is, how strict are they going to be in their interpretation of their own specs.
208 volt, 3 phase is not an option, though I wish it was. Voltage drop is also an issue that I will be taking into consideration. Grounding, transformer taps, etc, etc, etc will all be considered.
Bj, thanks for the input, and if the rest of this job goes as the first few weeks have, drooling will be part of my daily routine.
Drool Rag in Hand,
Doc
