Refer to Figure 1. What is the total load a feeder serving four 2hp motors, three 5hp motors, one 15hp motor, and one 25hp motor? All motors are 208V.
a. 50A
b. 145.2A
c. 201.1A
d. 219.8A
d. 219.8A
125% of the largest motor’s FLA from NEC Table 430.250:
25hp = 1.25 x 74.8A = 93.5A
Add this amperage to the other loads:
4(7.5) + 3(16.7) + 46.2 + 93.5 =
30 + 50.1 + 46.2 + 93.5 = 219.8A
