If we have a panel with only 2 motors, these are the only loads of the panel. One motor has a Full Load Amps (FLA) of 50 A, and the other has an FLA of 25 A. According to NEC Article 210.19(A)(1)(a), the total ampacity for the main feeder panel is calculated as follows:
50*1.25 + 25 = 87 A
Therefore, we need a feeder that can handle 87 A. However, here's my question: what happens if the motors only operate for 3 hours per day? Since these are water pumps, they run 3 times for 1 hour each day.
50*1.25 + 25 = 87 A
Therefore, we need a feeder that can handle 87 A. However, here's my question: what happens if the motors only operate for 3 hours per day? Since these are water pumps, they run 3 times for 1 hour each day.
