Does NM Clamp exist for this situation?


Hello,

I'm hoping that someone can provide a suggestion for a NM clamp that will work in this situation. This metal conduit is going to a ceiling fixture. I'm looking for a method to secure the cable as it enters the box.

I attached a picture to illustrate. Thank you in advance.

No. You can't run NM inside EMT.

Depends on the length. A short section is ok provided it has a clamp on the transition point.

Remove the sheathing and leave at least 1/4" extended inside the box.

This is one code allowance (just remember it is for indoor scenarios only):

This is a very short run of EMT, maybe 6' of metal conduit and it's 3/4" ... The cable is clamped as it leaves the wall, but I was hoping to secure it at the box too. I'm aware of the debate about romex in conduit, but I was unaware this was a violation. My only other alternative is to tear down my ceiling and drill through a number of cross beams.

Very good.


This, or something similar would need to be put on the beginning of the conduit where the cable transitions:

I think you are ok. Short sections are allowed by code. As long as the cable is secured where it enters the conduit you are ok.

So as long as it's clamped as it enters the conduit, it doesn't need to be secured at the fixture box? It's already been secured where it enters the conduit.

The cable does not need to be secured in the box since that takes place where the cable enters. As long as the transition bushing is inplace you are ok.

As for the box itself this would be a nice compliment against the metal edges:
