Which of the following is NOT a standard ampere rating for a fuse or inverse-time breaker per 240.6(A)?
a.45 A
b.70 A
c.110 A
d.130 A
Explanation
The standard ratings in 240.6(A) include 45, 70, and 110 A, but 130 A is not listed (the next standard sizes are 125 A and 150 A). Knowing the standard list is essential for applying the next-size-up rule.
