I've seen this and was just wondering if there is any code against installing romex connectors in reverse. The locknut being on the outside of the box,panel etc.with the two screws inside.Thanks
If the Romex grips are on backwards the locking ring could be removed and the assembly made to be loose and push into the box. This would not be installed according to Manufactuers specifications.
I have done this in panels where I was adding circuits and couldnt get the romex connector in the knockout without having to do major wall repair. Much easier to slide a locknut over a knockout with a screwdriver and hold it in place that way so you can put the clamps inside the panel as it is to cut the wall and put the clamps on the outside of the panel. I have never been turned down by an inspector for doing this. On the other hand, I have never been told it was legal either.
One thing that I have learned on this forum is to try to be more understanding of the way other people do their work. Whenever I saw the 'romex' connector in 'backwards', I used to think it was the work of a homeowner/handyman. Now listening to your resolve of how you snake in the wire maybe it is not such a bad idea. I would say calling the manufacturer to find out if that falls into the methods they tested the fitting for could help decide if this is permitted.
I also have made a practice of installing an NM connect "backwards" in a panel when fishing cables in for added circuits. I'm not sure what the manuf. would say about htis but it sure looks and feels safe.
I've installed them backwards a lot of times when doing re-work and have never had a problem getting it passed. As posted, it sure does make it easier to get a connector on a fished wire to a flush mounted panel.
I've never needed to install tham 'backwards' on fish-ins. Either install the connector onto the wire before pulling it in, or back-cut the drywall at the top of the panel.
I have seen this done in meter sockets- the connector installed 'backwards' with the clamp part of the connector inside the meter socket. I have no idea why it was done this way, but I have seen it. Maybe so the hole through the wall didn't have to be cut as big??
add me on this list for backward nm installment also i do that with exsting box also but right now i am expermenting the plastic nm clamps to see if that go faster but really the time wise it was about the same amout of time as installing the convental way
