Additional cable-core marker

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.
