Mebbe 240.21(B)(5)?
Could the question have been to see if you knew how to apply that section?
50 or 100 would apply under 'unlimited length' rules.
Without knowing the exact question, it's hard to tell what they were looking for.
Perhaps the question was looking for an answer that is listed in 240.71(B)(5)1) through (4).
Was this in an open- or closed-book section of the test?
FWIW, some test questions are written with a specific error in the NEC in mind. They know there are people out there with wrong or missing sections, and they write questions accordingly, just to make you miss the question.
How about 430.28?i do have that section, but the thing is reading this whole chapter i do see any other lengths other than 10 or 25 ft and this article has to contain all the tap length imfo right
