While doing this, I noticed that the ground wire(s) in every outlet are twisted together and screwed to the metal gang box. The grounds wire(s) are NOT connected to the outlet's grounding screw. A few questions about this situation:This seems to be a casting of something. I got it in a box of traveling items. It looks like a dental cast but then also looks like an insect. It’s lightweight.

The grounding links the steel boxes. Then the steel boxes carry ground to outlets. On metal boxes, most receps self-ground. Once you have done that, you have a receptacle whose metal "yoke" (the ears the screws go through) making hard clean metal contact with the metal box; no paint, rust or little screw-holder squares in the way.It is indeed legal. That is what's known as a self grounding device. The little brass tab on the bottom screw hole that straddles the yoke screw will act as a ground if no ground wire is landed on the device itself. Assuming the box is metal and the box is grounded the self grounding works. If plastic or fiberglass this feature is useless. Especially if you are using the metal junction box as a self-made "extension cord" because if that box comes into contact with moisture getting an electric shock is a high probability. It is even more important to use the grounding screw on .

That ground wire from the .
