Over kill bond bushing

[jaggedben]

Thanks Carultch, that is what I was looking for.

Anybody disagree on the following statement?
ON DC SIDE, over 250 VDC, no GEC, a steel connector on EMT conduit with lock-ring (only) into an aluminum enclosure KO (not eccentric or concentric and no reducing washers) = code compliant?

I think it has to be the type of connector with teeth that scrape the paint off the aluminum. Or you have to scrape the paint off yourself.

See 250.12 and/or 250.96.

Seriously, I think it's okay, but I had an inspector ding my crew for this recently and I had to call him up and point out that it wasn't necessary because they used... you guessed it ... a bonding bushing.
