I never saw the NM EGC wrapped around the NM cable sheath to be squeezed by the clamp of a metallic box connector, with the notable exception of wiring done by unlicensed people. There was no end of creative "bad" installation done by them.

I was informed during my apprenticeship in the early 80's that this practice was called "The Boston Wrap" and I have called it that ever since then. We would remove the clamp and try to pull the sheathing through the box or get our needle nose and gently pull at the EGC unwrap it and bond it properly. Sometimes that EGC would be engrained in the mineral/ cloth insulation from the clamp pressing on it so tight.
Hopefully it was exclusive to the New England area.
Maybe someone from Massachusetts has heard of it?

Hmmm.....the Boston Wrap. I guess someone from Boston made their way to my area. I've seen this method hundreds of times in residential and commercial (apartment complex's) applications. At least now I have a name to put to it!:)
