314.23(B)(1)Nails and Screws. Nails and screws, where used as a fastening means, shall be attached by using brackets on the outside of the enclosure, or they shall pass through the interior within 6 mm (1/4 in.) of the back or ends of the enclosure.

I have seen different reads on this in various forums. I am posting some examples of what IMO is code compliant.

I am very interested in others opinions on this.

Picture One.

I believe this to be code compliant.

The nails pass through the interior within 6 mm (1/4 in.) of the back of the enclosure.

Picture Two.

I believe this to be code compliant.

The nails pass through the interior within 6 mm (1/4 in.) of the ends of the enclosure.

Picture Three.

I believe this also to be code compliant.

The screws do not pass through the interior at all, the screws pass through the exterior of the enclosure.

That is my interpretation of this rule, so bring it on how do others see it.

I do not use any of the above methods for mounting I am just curious.

OK I have put screws in a 4" sq as shown in picture three. [Linked Image]
