## Symbol convention

Convention: IEC
Form: Additional cable-core marker
Autodesk IEC-60617 Symbol Preview — Cable identification and twisted-pair annotation; vendor family reference, not certified IEC geometry or database identifier.

An additional-core marker associates another conductor with an existing cable record.

## What it represents

An additional-core marker associates another conductor with an existing cable record. A child or additional-core marker expands the same cable identity to another conductor. It should preserve both the parent cable association and the unique core designation.
Check the parent/child association when copying or moving circuits. The additional marker is another view of the cable, not another cable to procure.

## How to read it

- Link it to the cable parent and preserve the individual core identity.
- A child cable marker should not be counted as another physical cable.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Link it to the cable parent and preserve the individual core identity.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

A child cable marker should not be counted as another physical cable.
