I'm using NM clamps on cables going into knockouts in a metal box. The box is coated with a protective coating. The NM clamps' description says that its locknut is, "designed to cut through protective coatings on boxes and enclosures to assure ground continuity." The box I'm using has threads...

They had to cut access panels because the metal frame that the can and box mount to is much too large to go through the 4" hole for the can. Yes, the problem I'm wondering about is the wafer type where the transformer sits on the ceiling.

Here's what I'm seeing in the house where I'm working: The can lights were remodels, but access panels were cut into the drywall during installation (and later patched) to get everything into the ceiling. There is a metal frame that braces between the trusses. That metal frame has a ring...

Right. In most of the LED wafers I'm seeing, the driver is inside a box where you can make your splice to the 110v line. That's what I was calling a driver/junction box. The common method seems to be to just put that box in the ceiling unmounted. My question was: is that up to code in the U.S.?

There does indeed seem to be a gray area, at least in application. There are dozens of YouTube videos, including instructions *by light manufacturers* that show installation of LED wafer lights where the driver/junction box is just placed into the ceiling.

It's not. The box and the can are both attached to a mounting bracket. As someone else pointed out, the code specifies that it can't be necessary to remove part of the building to access a box, not that there be no "obstruction". This should be obvious as boxes are routinely "obstructed" behind...

Incorrect. I'm working right now on some low voltage halogen can lights that have a junction box that's only accessible once you remove the can.

I appreciate you doing the research and finding the actual code. Do you happen to know whether the box has to be mounted, or can it just sit on the drywall in the ceiling? I'm talking here about the junction/driver box that comes with an LED wafer light.

This doesn't make sense. Pretty much all low voltage can lights I've ever seen have a junction box and a transformer in the ceiling that's only accessible by removing the can.
