Are you saying that the original install did not have connectors on the MC?
Is ther any connector like that which can be used with mc cable?
I was in a supply house the other day and some company makes a old work ring that is rectangular and is cut into the sheetrock above the panel. Then it has a white finish cover when you are done that snaps into place. If you can picture that, I guess it's about 14"x4".
Arlington makes it I think.
Actually I have used those before in new work but I've not had much luck getting them through the knockout once the wire is in them. It's the wire that spreads them out so they stay in. Now that you mention it, I suppose I could try to force one in with the wire in it and see what happens. Thanks.
I sometimes cut a hole for an old work box, install the box and blank it off whien I'm done. But I like your idea better.I was in a supply house the other day and some company makes a old work ring that is rectangular and is cut into the sheetrock above the panel.

I forgot to say the way I was talking about using the 3/4 plastic wont pass inspection if the ahj is alert because the clamp is holding the wire in the wrong direction
That is something I've always thought about when it comes to connecting to the panel. When it comes to NM cable why is it so important to clamp or squeeze it at the entry point? It's buried in the wall and stapled down the line so it's not going to move. It would seem to me any kind of simple grommet to protect the wire from the sharp edges of the metal would be sufficient. It's not like the wire is a structural component that's going to hold the house together in a 200 MPH wind storm.
NM doesn't have to be clamped or squeezed in all cases, take a look at most single gang nail on boxes, there is just a KO for the romex to come thru, no grommet or any other protection.
In the case of this thread, the wire fished down to the panel wouldn't be supported in the wall, so it would need some type of clamp.
In that case you are required to secure the cable within 8 inches of the box instead of the 12 that is allowed in practically all other places.
