Is this a typical installation? I have never seen in a while in use cover the exposed wire from the cover to the device. I know the ground is harmless but this does not feel very secure.

I agree with Infinity. The instructions say a ground wire is included and the receptacle mounting screw should pass through the eyelet, IOW's make contact with the device yoke, the way it's installed in the picture is wrong.

Thank you for the response. What does the acronym for IOW mean?

In Other Words, the apostrophe and s was wrong too 🙂

That thing is ridiculous. There should be no wire running around outside of the cover like that. How long do you think it will last? Looks like an afterthought to get it to pass UL. o_O

Presumption is this bonding jumper would allow the metallic cover to be used with the NM enclosure as there would be no other contacting point to provide grounding continuity to the cover in such installation. Normally a NM box would require a NM cover. Seen a long time ago other metallic covers that had a bonding jumper attached as a riveted eyelet at the cover screw hole.

OP image is an example of an installer that didn't understand grounding and bonding as that side screw doesn't provide for the bonding of the EGC that is as infinity suggested should have been on the center screw associated with the receptacle strap bonding.

I think kind of ingenious adaptation by Intermatic that would allow the use of the extra duty metallic cover on an installation that had a NM box.
