Protection/NEC

[a4u2fear]

If there is an NEC question on sizing a circuit breaker, is it considered a code and standard question or a protection question; or both?

I always considered questions that specifically request usage/reference of NEC as a "Codes and Standards" subtopic under "General Power Engineering". Otherwise, if there is no mention, I would consider it to be a "Protection" question under the "Transmission & Distribution" topic.

But, I don't know, it certainly could be both.

If you're asked to size a breaker I would see that strictly as an NEC question. They typically will say "in accordance with the 20XX NEC" though so that should help. The only way I see them asking for the size of a breaker and it being a protection question is if they give you several sizes of breaker in the answers and you have to pick the right breaker that coordinates with the rest of the system.

I think they count it as NEC codes and standards as far as the # of questions on the syllabus.
