I've got a lot of electrical panels with conduit entering through holes that have been drilled across concentric knockouts. We'd like to add bonding bushings to these but would rather not have to "unwire" the whole panel to feed the conductors through the bushings.

I know I've seen bonding clamps or clips that slip under the locknut where the fitting enters the panel. I don't know what to call them and can't find them now. Maybe they were never legal, I can't even remember where I've seen them. But I'd like to find an easier way to add bonding.

Hoping somebody has a great idea.

Does that slip under a bushing?
It looks like the opening is not large enough to slide in from the side; but would have to be treaded over the end of the conduit.

exactly what I was looking for. Will require removing any bushings/locknuts from the fitting but I won't have to pull all the wires through the wedge.

Just called the electrical supplier and they said "A what?" but found it with the T&B number on the pdf you included.

Thanks.

From my experience, if you have a plastic bushing you'll have to drill a hole in it to get the bonding screw into the thread of the conduit

The pdf file Greg posted from T&B shows a "T&B Series 122 Metallic Bushing" below the wedge.

I wonder if this is part of the bonding wedge's listing.
