Greetings all,
To be compliant with 250.146 (b), I had thought that those receptacles listed as self-grounding never had the little insulating washers as they would inhibit the metal to metal contact. At least they didn't years ago as I recall when I used to work in the trenches. In reading 250.146 (a) however, it would seem to indicate that you could be allowed to remove one of the insulating washers and the receptacle would be considered as grounded as long as it's listed as self grounding? I just don't remember ever seeing receptacles listed as self grounding having insulating washers? Am I missing something here? All of the self grounding receptacles I ever saw never had those washers. It has been a few years since I've even thought about and the subject came up today on a project.
thanksabunch
