Correct answer to question 8036
- C: The largest branch-circuit device rating plus the sum of FLCs of the other motors
Explanation
Section 430.62(A) limits the feeder device to the largest rating of any branch-circuit short-circuit and ground-fault device in the group plus the sum of the full-load currents of the other motors. Unlike branch circuits, the feeder rule does not allow rounding up.
