You sure that enclosure question is correct?

I had something like what is the maximum permissible gap around a cable as it passes through a wall/floor. The answer to that is 527.2.1

Can't remember the exact wording but i'm pretty sure it was about the CSA of cable allowed,and it it also mentioned enclosure and non-fire protected,but you may be right.

Thnks for that T@E. That sounds about right.I put 0.5 x current rating which can test for earth leakages,but probably wrong.
Hopefully I got about 60-70% so I may have scraped through.Got 86% in my 302 and dist in 301
