Earth grid conductor

Earth grid conductors are bare horizontal conductors buried under substations and plant areas to control step and touch voltages during faults. Layout drawings show them as a distinct line style, with crossings, connections to equipment and rods marked along them.

Drawing use: GA
Application: Connections & wiring
Reference family: IEC / IEEE / ANSI

A distinction that matters

An earth grid conductor is a buried horizontal conductor; an earth electrode is a rod or plate in the soil.

Earth electrode

The earth electrode symbol marks a rod, plate, tape or foundation electrode that makes contact with the general mass of the earth. It appears on earthing diagrams and site layouts, often numbered so that individual electrodes can be tested and recorded.

Drawing use: SLD / GA
Application: Connections & wiring
Reference family: IEC
Form evidence: Earth electrode. Independent IEC-context illustration; not certified IEC geometry.

A distinction that matters

An earth electrode is the physical contact with soil; an earth connection symbol is any connection to the earthing system.
