A feeder must supply a continuous load of 32 amperes plus a noncontinuous load of 40 amperes. What is the MINIMUM feeder conductor ampacity required?
a.72 amperes
b.76 amperes
c.80 amperes
d.90 amperes
Explanation
Continuous load is taken at 125 percent, so 32 x 1.25 = 40, plus the 40-ampere noncontinuous load gives 80 amperes minimum. Simply adding 72 ignores the continuous-load factor, and 76 or 90 misapply it.
