Thanks all for the replies.

BTW I got my permit in 2006 at which time my county was using NEC
2002.

I will definitely be using the grounding bushing to insure box-to-
conduit ground. John mentioned to use the grounding bushing after the
locknut. Couldn't the grounding bushing be used by itself? The ones
I've seen are pretty beefy compared to the locknuts. Is it code or
personal preference that you use both?



I've always used the locknut then a bushing. I guess you would have to find
out from the manufacturer if their bushing was approved to function as a
locknut would. You may find that the bushing will not screw all the way
down enough to lock the pipe in place.
