Refer to Figure 1. What is the total load of a feeder serving four 230V motors rated 5hp, 15hp, 20hp, and 40hp?
a. 80A
b. 90A
c. 215.2
d. 241.2
d. 241.2
125% of the largest motor’s FLA from NEC Table 430.250:
40hp = 1.25 x 104A = 130A
Add this amperage to the other loads: 15.2A + 42A + 54A + 130A = 241.2A
