Talking Please explain what U-grounded means

Could anyone explain what a U-grounded receptacle is? I found some described this way but I'm really looking for quite a few self-grounding 115v receptacles. Is that the same thing? Thanks for your help.

I have never seen the term 'U-grounded', however electrical terms are often regional. Could you provide some context? Are these an item on e-bay or some such?

Also, you use of the term 'self grounding receptacle' raises a red flag for me. In what situation are you planning on using these?

Often in the construction trades, a common household-type receptacle is called a "U-ground" (because it sort of has a U shape) to differentiate it from a twist-lock receptacle which is also very common on construction site temporary power equipment.

U-ground could have different meanings depending on context.


An ungrounded receptacle has no U-ground.

A self-grounding receptacle has spring clips on the yoke and must be installed in a grounded metal box.

A U-ground recepticle is one that has a U shaped grounding hole, which all modern domestic recpticles are. As opposed to other shaped grounding holes, from back when they started worrying about grounding appliances.

Self grounding is a separate feature, described in another post, and often included on other style recepticles and non-recepticle devices.
