The ampacity of conductors from a generator terminal to the first overcurrent device must be at least what percent of the generator nameplate current rating?
a.100%
b.110%
c.115%
d.125%
Explanation
Section 445.13(A) requires the conductors from generator terminals to the first distribution device to have an ampacity of not less than 115 percent of the nameplate current rating. This margin covers the generator's ability to deliver current above its continuous rating; 100 or 110 percent would be insufficient.
