Was 310.4 removed from NEC 2017 book?

[Teague Allen]

I had a test prep question for parallel conductors and the answer says to check 310.4(A) but there is no 310.4 it goes from 310.2 - 310.10 I looked through article 310 and didn't find anything that was a part of 310.4. I know this is probably a dumb question but I cant find it.

The 310.4(A) reference for parallel conductors is from the 2008 NEC.

Article 310 was revised to be align with the parallel construction used the the Chapter 3 articles in the 2011 code. Using conductors in parallel is a "use permitted" so that was moved to 310.10. It was in first level subdivision (H) for 2011, 2014 and 2017. It is in (G) for the 2020 code.
