Correct answer to question 3015
- C: One-third of the feeder OCPD rating
Explanation
Taps not over 25 ft long must have an ampacity of at least one-third of the feeder OCPD rating. They must end in a single circuit breaker or single set of fuses that limits the load to the tap ampacity. See 240.21(B)(2).
