I hate RE plates. I would rather screw a plate in the can and make sure there is a ground wire. I have had inspectors fail an installation; he wanted reducing washers; I had bolted a cover plate to the top of the box and had a grounding bushing and ground wire in the EMT. My way was better and I proved it to him with a megger. He made me change it to pass inspection. Still scratching my head Rod.
