wire protectors, nail plates

[Buck Parrish]

I have a customer that ran wiring in a log home. He ran the wires surface mounted in between the logs. Then the mud will be put on top of them.

Then he calls me:-?.
Would a long piece of metal 2'' wide an 4' long suffice as a nail protector? It would also keep the mud from direct contact with the wires.
The boxes are made up so conduit would be a pain.

It seems the question is really, "What type of wiring was used?" EMT, MC, Romex? I dont think there is a problem with the type of studgaurd you use as much as there could be a problem with the wiring system. Romex or MC would probably not be acceptacle. I would say if the wire is emt, it may be ok .

I've never have an inspector turn me down for non-ul listed stud guards.

Why would EMT require a nail plate?

It's #12 indoor wire nm (romex)

Thats not what i said. What is said was you cant shove a bunch of wet concrete around a romex wire or an mc wire for that matter.

Buck look at article 334 in The NEC.

Just what are you putting over the romex ? And how thick ?

 

[infinity]

If the metallic steel material is 1/16" thick or greater than listing isn't an issue.

My guess is chinking.

 

[dcspector]

My guess is chinking.

I agree you old f*rt.... and I remember that terminology as well. That is what it is called. I am looking at 334.12(B)

Why would it require a nail guard at all? It's a log home, you're not hanging drywall or putting up any shear panels. I wouldn't even worry about it. If I had all the wood to attach something to, I'm going to try to go out of my way to not hit the chinking.

John I am now confused is it protection of NM or embedding the NM....?

 

[macmikeman]

If the cable is not subject to physical damage for whatever reason log houses might afford, (I never saw the inside of one so I have no idea of the space where the logs meet.) then covering with hat track should be a good way to provide a barrier between the romex and the plaster goop they are slapping on top. If there is a physical damage chance due to 1-1/4" issues, then hat track is not heavy duty enough.

The OP said nail protection, then others got off on embedding. Now without looking it up and never having done a log home, I might have to think about the embedding, part.
