Just hope for someone to look over my numbers and see if I am on the right page.
Control Panel with
(1) 50 HP Motor 65A FLA @ 480
(8) 1 HP Motors 2.1A FLA @ 480
Feeder size Based on NEC 430.24
(65A * 1.25) + (2.1 * 8) = 98A Minimum (Select #3 THHN)
Breaker Overcurrent Protection Based on NEC 430.62
(65A * 2.5) + (2.1 * 8) = 179A Maximum (Select 150A Breaker)
Ground based on 150A Breaker and NEC 250.122
#6
I just want to clarify that this is not considered a tap and the NEC doesn't have any distance limitations on the feeder length.
Thanks Ahead of Time,
Steve
