UL Listed romex connectors in recessed cans
I tried to wend my way thru the responses here and..,I don't know -guess I lost my head-I'm an inspector and this seems like much adoo about nothing.!
The article referenced by the inspector does not come into play at all here.
The two code possibilities would be either "conductors entering a box ,enclosure,panel etc,and methods of securing as per type of conductor and type of box" or "manufacturers installation instructions". Both of theses possibilities allow for proper installation of RX conductors in a code compliant manner utilizing the manufacturer supplied clamps,inserts,strain relief ,etc ,methods.
In other words-you can install RX in a metal jem box using the supplied knockouts and clamps and it will be legal and safe.If you run your finger around the entry edge will you possibly find some"flash"?
Answer -yes, but that is not in itself a code violation.
The correct install method[having the RX sheath enter and be secured under the clamp method so as to act effectively as a 'bushing' allows the installation to be code compliant.
