When using NM cable with metal boxes, does the code state the cable must be connected (attached, whichever) to the box (as if with a connector in one of the knockouts)? I looked but couldn't find it. Seems that the same would apply with plastic boxes. [Edit: Yes, with exceptions for non-metallic boxes. 314.17(C)]

This is a stretch from discussing bonding/grounding, but, if a metal NM cable connector is used in a plastic box, does it need to be bonded. If yes, then all the more reason not to used a metal connector with a plastic box.

The box with clamps most people would use the clamps
The wire must be secured within "x" inches of the box depending upon the circumstances
No requirement to fasten it to the plastic box

A metal box is totally different
They usualy have clamps built in to secure the wire

I don't know anyone that would use a metal clamp on a plastic box
Added expense & not needed
