Socket outlet with protective earth contact

On an installation plan this mark places a socket outlet whose contact set includes a protective earth pin or earthing clip. The basic half-circle outlet form is completed by a straight bar across the top of the curve, which tells the reader that the outlet connects the protective conductor of the final circuit to the plug.

Drawing use: GA
Application: Installation & communications
Reference family: IEC
Form evidence: Socket outlet with protective contact. IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

A distinction that matters

A plain socket-outlet mark shows an outlet position only; the earth bar adds the protective contact. The protective earth terminal symbol itself is a schematic conductor mark, not an outlet.
