Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

Symbols

Shield-wire earth termination interface

Identifies the assigned termination of the overhead shield-wire earthing path at the station. Earthing and lightning interfaces identify the connections between equipment metalwork, primary protection devices and the station earthing network. Their electrical purpose differs from their physical conductor route or electrode geometry.

A distinction that matters

Current distribution depends on the complete earthing system. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.

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.

A distinction that matters

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