Has anyone encountered an inspector that requires metal protection plates to be added to steel studs when using NM. The inspector says that the steel studs w/grommets can be less than 1 1/4" from edge because they can move, therefor the NM would be in danger of penetration from the drywall screws. For the record I am an inspector and this is happening to one of the Township supervisors that also happens to be a commercial builder. I think this is crazy but its happening outside of my jurisdiction. Thanks!

No I have never heard of this, unless the sheetrockers like to waste money they will not use screws that have an extra 1 1/4" of length. Around here for 5/8" sheetrock the rockers use 1 1/4" screws so only a 5/8" sticks thru the stud.

Is the Pennsylvania Electrical Inspector using this NEC rule to support his enforcement of the requirements?

Quote
300.4(B)

(2) Nonmetallic-Sheathed Cable and Electrical Nonmetallic Tubing.

Where nails or screws are likely to penetrate nonmetallic-sheathed cable or electrical nonmetallic tubing, a steel sleeve, steel plate, or steel clip not less than 1.6 mm ( in.) in thickness shall be used to protect the cable or tubing.

Likely?? .... this is vague and undefined and probably violates the NEC Style Manual

I guess we have a lot of work to do. The word "likely" shows up 79 times in the 2002 code. I do agree that it is very vague and should be removed from the code.

Don:

Here's a list from the "NEW 2003 NEC Style Manual" and the word "Likely" is included!

A comment to a proposal with these terms could be added when the ROP becomes available.

I am in Mesa, Arizona now and just about to start a class, and wondered if anyone who has the 2002 NEC electronic copy could do a search and show how many places these "Vague and Undefined Terms" show up ...
