I have a 480 3ph step down transformer feeding a 120/240v panel twenty feet away.
The feeders are 4 - 4/0 with ground. The panel is suppling electronic games and has a full 42 circuits in it with seperate nuetral for each branch circuit. The problem is the nuetral feeder is pulling 250amps and is warm to the touch. The phase conductors in the feeder are pulling 180 to 190 amps and are hot to the touch. Any ideas on why the phase conductors are hotter than the nuetral and how to fix?
