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.

IEC

Removable earth test link

The earth test link sits in the earthing conductor between the main earthing terminal and the earth electrode. Removing it isolates the electrode so its resistance can be measured on its own. Installation guidance describes it as part of the earthing arrangement at the main earthing terminal.

A distinction that matters

An earth test link is removed only for electrode testing; a neutral-to-earth link bonds neutral and earth in service.
