A PE terminal provides a documented protective-conductor connection, often including a specified connection to the mounting rail.

## What it represents

A PE terminal provides a documented protective-conductor connection, often including a specified connection to the mounting rail. The circuit and terminal plan must show the bonding path actually relied upon.

## How to read it

- Trace the protective path to the assembly's earth connection.
- 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

- Identify PE terminal
- Show rail/bonding connection
- Reference terminal suitability

## Important distinction

A PE terminal is not a signal-common terminal.

## Facts

- Drawing role: Wiring interface
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- 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.
