CalculationsQuestion 14 of 110
A single continuous-duty motor has a table full-load current of 34 A. What minimum conductor ampacity is required for its branch circuit?
a.34 A
b.42.5 A
c.40 A
d.50 A
Explanation
Motor branch-circuit conductors must be at least 125% of the FLC: 34 A x 1.25 = 42.5 A minimum ampacity.
