A bonding locknut can be used for grounding service conduits ahead of the main.
They can't be used if there are KO's left because the angled screw on the locknut sets into the concentric KO's and not a solid piece of metal on the enclosure.
Anyone get an answer from UL or manufacturer yet?
I also would like to mention that a bond bushing will not fit far enough onto the threads of a Myer's Hub in order to properly set the set screw into the threads.
