Don,
Not sure which Glenn you are mentioning.
On my post, I mentioned " Only one end of the metal "Service" raceway needs to be so bonded".
I did slip-up on the complete info about the set-screw locknut. A set-screw locknut is not allowed when concentric/eccentric KO's are envolved.
On enclosures for Service conductors, see 250-80.
Only 250-64(e) for a metal enclosure for a GEC needs to be bonded to the GEC at each end and to each enclosure the GEC is in.
Glenn
