A cable marker is a symbol that indicates the wire it is on is part of a cable.
A cable marker carries a component tag value, similar to any parent/child device combination. It also carries a conductor color value on the RATING1 attribute and a gauge value on the RATING2 attribute of the marker block symbol. The parent symbol can carry catalog part number information. If the cable is referenced in the cable conductor database table in the catalog database, the application can track the conductors used and the conductors available.

Multiple Cable Markers
AutoCAD Electrical toolset provides a way to insert all the markers for a particular cable from one dialog box. In addition, you can edit existing cable marker sets, or even delete cable markers from a single dialog box.

This tool first extracts components and wiring. Then you select "From" and "To" location code combinations to report. AutoCAD Electrical toolset filters and formats the wiring and connected component data and reports each wire and what is connected at each end. Components that have no assigned location code are grouped under a generic "(??)" code. Component wiring that daisy-chains along a common bus (for example, hot or neutral bus) may not report in the connected sequence you expect. (You can use the AutoCAD Electrical toolset Wire Sequence command to define wire connection sequencing for wire networks that have three or more interconnected components).
