An earth connection identifies a documented circuit connection to earth.

## What it represents

An earth connection identifies a documented circuit connection to earth. The drawing's label and context establish whether it serves system earthing, protection or another specified role.

## How to read it

- Read the connection's purpose instead of treating every earth mark as interchangeable.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- State connection purpose
- Identify earth conductor
- Reference earthing arrangement

## Important distinction

Earth, protective earth and functional earth have different documented roles.

## Facts

- Drawing role: Earth or bonding role
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HGND2, VGND2 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
