Hello everybody,
first of all i'm a DIY and love to understand what i don't and learn how to do things by myself,
so please don't give me the usual "find an electrician"
I'll find an electrician, but i want to have it all figured out before it happens
So here is the deal, i want to wire 2 industrial buildings with 600 Amps each, 120/208 volts Wye, but here is the problem the length from the meter to the distribution panel is 120 feet at least.
Voltage drop calculations give me 500MCM aluminum wire 2 conductors per phase in parallel with 1.67% VD . Quite an enormous amount of connectors for 120 feet.
Could Using smaller conductors and a transformer reduce the amount of connectors and give better results?
If yes what kind of transformer (auto, multiple winding, buck boost, etc..) and what conductor size could be used?
NEC Table 310.16 gives me 4/0 wires with one conductor per phase at 205Amp per wire...
Thank you
