1 and 2 comply, 3 does not, in my opinion

I do not understand why you feel this way, I am not saying you are wrong I just need some more info.

The key to this in my opinion are the words:

"pass through the interior"

The screws in the side of the box do not in any way pass through the interior of the enclosure.

Pass to move in a path so as to approach and continue beyond something

Through used as a function word to indicate movement into at one side or point and out at another and especially the opposite side of <drove a nail through the board>

Interior the internal or inner part of a thing

All the definitions came from the Merriam-Webster On line Dictionary.

So that is why I have a hard time with this article, we would have to change some of the definitions in order to enforce the section the way you want to.

That said I will keep an open mind, maybe I am missing something.

The 2002 handbook is no help at all for this, I would call the handbook commentary after this section gibberish. [Linked Image]

This requirement prevents the nails from interfering with the installation of devices. Permitting nails inside the box within 1/4 in. of the ends reduces splitting of the smaller wooden studs used in some frame-type construction. However, splitting sometimes occurs where nails are within 1/4 in. of the back of the box.
