Hello
If we upgrade service from 120/277 3 phase, 4 wire to 480/277 3 phase wire, size of conductors get smaller. My boss says to me that the utility bill will go low as well because of I2R losses in the conductors.
As Size of conductor is smaller, its resistance is small, which leads to lower losses.
I don't think it going to make any impact. It makes impact in transmission lines because of long distance.
Resistance is directly proportional to length and square inversely proportional to area.
I dont think its large area difference between #10 & #6 wire.
Please help
