OK so for 2005 it is clear screws are out unless protected by sleeves. [Linked Image]

This also proves that they are taking about screws that pass through the interior of the box. If the screw did not pass through the interior it would not need protection.

When I read the code, it gives me two options on how I can support a box with internal screws.

Option 1: I use brackets outside the box.
Option 2: I use screws that pass through the box, within a 1/4" of the back or ends of the enclosure

OK so the following box is a code violation, the screws do not pass through the interior of the box.

I maintain that 314.23(B)(1) as written now or in 2005 only applies to screws that pass through the interior of the box.

If it applies to all box mounting methods the common mounting method is a violation.

As you said before in another thread "by using the English language" can you explain what part of the screw in the 4" sq above passes through the interior of the enclosure.

Please remember to just read the words in the section, not read what you want it to say. [Linked Image]

Still just a curiosity for me while I am sitting here babysitting watching Sponge Bob. [Linked Image]
