Don't see why not... assuming the rivet is of the right size, and is properly installed.
I'm not going to focus on the rivet body as a 'conductor,' as it is my belief that a firm connection will result in current going directly from the wire, into the metal case... without any need for the rivet to conduct at all.
Do you have insomnia and lie in bed at night and think these questions up? Actually it’s a good question. Who’s to say if a bolted connection is any better than a rivet if both are applied right? I have seen riveted grounding or bonding connections as you’ve described on UL listed equipment. That would indicate to me that it could be an approved application as long as the connection was made properly and to the manufactures’ specifications.
By the way gents, I am new to these boards and am an electrical inspector in the same area as George is. He is my mentor, very knowledgeable and a great guy. He has taught me a lot and has answered many questions when I’ve needed help. I’m looking forward to these discussions and have enjoyed lurking in the background.
