I punched something in real quick and used all appropriate articles without a calculator for the moment til tonight. Can you check my math
Running new feeder off a 3Phase panel 120V/208V off a 90 or 100 amp 3 phase OCPD.
Will be feeding a 125 amp load center with 2 - Machines. 1- 60 amp single phase (MCA 56amps), 1-70 amp (MCA 66 amps)
Does running a #2 or #1 4 wire off a 90 amp 3 pole or 100 amp 3 pole sound correct?
Machine power coming mostly from heaters
Total Load (32,400VA)
15,600 amps phase A
7,200 amps phase B
7,200 amps phase C
Question is #2Al 3 pole 90 or #1 3 pole 100 amp breaker for feeder ?
These numbers are crude and may be off a bit. I"m having trouble with the unbalanced load determining my main ocpd right now for some reason.
