I am setting up a small-ish communications facility (18 racks), that initially will not be anywhere near fully loaded. I would like to make use of the 3 Phase setup the building already has. I estimated that the maximum draw of that many racks is about 90KW, or 432A @ 208V. If I split the load as evenly as possible, and I am running at max (90KW), what is the voltage and amperage that the lines will see (as in what size conductors do I have to use, I would like to use the 2/0 wire I already have, but I realize that this is probably not possible). Do I then need to have 5 wires run, 3 hot, 1 neutral, 1 ground, and do they all need to be the same size conductor?
I somewhat understand the difference between delta and wye, but at this point I am not completely knowledgeable about any of this.
Thanks for any help!
