Gentlemen & Ladies (if it applies) Since I was the one who started this war, I guess I should make a comment from time to time so you know I'm monitoring. I just looked at the 2008 Analysis of Changes published jointly by IAEI and NFPA and maybe we can get a uniformed understanding after reading what it says on p. 132. For those of you who don't have a copy, I think they realized that there is this problem and they are trying to fix it by adding a new last sentence to 250.146(A). They are saying that if the receptacle is riveted or installed with some sort of thread locking or screw locking method it does not need a jumper installed between the green screw on the receptacle and the metal box. Nothing about the cover and receptacle being a Listed combination.
Works for me.
