Lets see - what code section(s) could this be

[Pierre C Belarge]

Did you notice the first picture? The contractor supported the box to wood that has been support to another piece of 2 x 4 - which I believe is supported to a wall stud.

Pierre,

It doesn't appear that would be permitted by 314.23, but I have never seen any other support used for a box in a masonry surface.

314.23(G),Enclosures in Concrete or Masonry "An enclosure supported by embedment shall be identified as suitably protected from corrosion and securely embedded in concrete or masonry."

One of the problems with using the handbook on the computer...sometimes when I come to the comment section, I don't scroll down.

No problem Sir, I really respect your intelligent.

Doesn't the buildnig code have a general requirement that any wood in contact with masonry be pressure treated?

You'd have to. I don't think there are any on the market now that aren't so rated.

It's moot because the NM shouldn't be there in the first place, but Halex 3/8" are rated for two 14/2s but only one 12/2.

Maybe it's me, but the box in pic #1 looks like it has a crack on the left-hand side.

 

[LawnGuyLandSparky]

The box in pic#1 is held to the 2x4's with sheetrock screws.

Do you install a box on the exterior wall of a wood framed house to supply an outside light fixture, using NM cable? Or do you supply those light fixtures with UF cable?

I was wondering myself were Tallguy was going with that comment...

duplicate - should have read whole thread first... sorry!

NM, but I can see an argument against that.

I was wondering myself were Tallguy was going with that comment...

I was referring to this pic, not the first one, since it is the only one with two pieces of NM on it:
View attachment 874

#2 & #3 lets see nm exposed to moist conditions even inside of conduit.

NM cable in wet location.

I'm with LawnGuy and cschmid.

...the NM cable is a violation in pictures 2 and 3.

Oh yeah, and Ryan too.

Maybe I've been caught up in all this "interior of a wet enclosure/raceway in a wet location is considered wet as well" talk we've had recently? Doesn't look like a dry location to me, therefore no NM. To my eye this is different than Pierre's scenario listed above...

So are you calling the interior of your walls a wet location?

No... talking about Pierre's photos of a stone wall....

 

[cschmid]

with the box in concrete and on the exterior wall it will sweet with temp changes and it wont care if it is rated for the use..so the paper wrap will definitely take on moisture over time..whether it does any damage in a reasonable period of time is the question? Has anyone ever tested it to see how long it takes for nm exposed to the weather to deteriorate?

 

[ZZZ]

Lets see

Lets see

1. No connector
3. Wrong ground screw, not w.p. box
2. I don't know, is that a metal connector?
Liquidtight in concrete? That does look like a crack now that you mention it.
nonmetallic bushing where cable enters conduit?

I haven't, but a neighbor up the block put about a dozen pagoda lights in a short masonary wall around the perimeter of the backyard using 12/2 NM. Back around '85 or '86 and they're still working. (Direct buried the NM) Don't know if the install is GFCI protected.

I still say and from my post #5 that the LFNC 90 connector is going to be concealed in the masonry. NEC 356.42
