I just got into an disagreement with an inspector, on this article.
So I have a manufactured homes kitchen remodel one side of stud wall exposed that only has 2” stud walls. I can’t get 1 1/4 spacing on framing members. Told gc to fur it out. Told me he would see what inspector says. He passed it.
I called him up and said I don’t have 1 1/4 spacing on each side of the framing member.
he said since other side of the wall was not taken off I don’t need the 1 1/4 spacing from there. That I can slap the wire right next to it.
I don’t believe it. I don’t interpret it that way. If it was not exposed I could get by but since it is exposed I have to meet 300.4.d on both sides of framing member.
Thoughts
 
The primary purpose is to keep the cable set far enough back so that it won't get damaged when the drywall is installed. A secondary purpose is so that after the wall is finished it may keep someone from driving a nail into the wall, missing the stud and hitting the cable. That code section mentions that the 1.25" setback applies when the cable is concealed which is what you'll have when the wall is finished.

300.4(D) Cables and Raceways Parallel to Framing Members and Furring Strips. In both exposed and concealed locations,
where a cable- or raceway-type wiring method is installed parallel to framing members, such as joists, rafters, or studs, or is
installed parallel to furring strips, the cable or raceway shall be installed and supported so that the nearest outside surface of
the cable or raceway is not less than 32 mm (1 1 ∕ 4 in.) from the nearest edge of the framing member or furring strips where
nails or screws are likely to penetrate. Where this distance cannot be maintained, the cable or raceway shall be protected
from penetration by nails or screws by a steel plate, sleeve, or equivalent at least 1.6 mm ( 1 ∕ 16 in.) thick.

That is what I thought. He said I can take it above his head if I would like but I don’t want to step on toes for a simple job.

I got a forum from a member that states “this is not code and is not safe.”
they sign it..
I am worried if I do that then come back and install the outlets that down the road they could come back and say “ if it was a problem why did you continue to work after the fact.

I was hoping I could point out a problem and the inspector notes it but he does not agree that it applies

Is that the building or electrical inspector? If the latter, then you're technically okay.

I would recommend notching the studs and using oversized nailing plates.
 
I've seen various inspectors go either way on "the other side of the wall" issue.

I got failed once because boss sent me some of the crappiest help I never wanted, and they drilled holes all over the place - up, down, in, out...it looked hideous.

Inspector said the wires were too close to the other side of the wall, which was an outside wall. He contended that trim could be nailed, etc, and nails could hit wires. He was right.

He demanded that the siding be removed and install nail guards. I suggested a better route - how about I pull the wires out, re-drill holes right, and pull wires back in. He said "that's what I was getting after"

Other inspectors seem oblivious to those kinds of issues

thing is I did not want it to pass. I wanted the wall furred out to be proper so no one can latter come back and say it not right why did you do it

That's why I asked which inspector. Your work is under the auspices of your inspector.

He's the one with whom you should have any further discussion about it, in my opinion.

I'm not disagreeing with your judgement about the install. Just decide how important it is to you.
 
If I'm running parallel to a thin stud, I'll trim up a few Stak-Its (or similar), fasten to the stud creatively, and put cable(s) in the slot farthest from the stud
 
I thought about those options for getting off-the-Stud. I think I’m just gonna tell the GC to Fur it out or I’m not coming back.
Thanks for the replies to reassure the way I was thinking was correct
