IEC

One-line cable identification

A one-line cable marker identifies the cable represented by a simplified connection line.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEC / Manufacturer
Form evidence: One-line cable identification. Autodesk IEC-60617 Symbol Preview — One-line cable-marker representation; vendor family reference, not certified IEC geometry or database identifier.

A distinction that matters

A one-line cable marker can stand for multiple cores and does not state conductor count by itself.

Symbols

Terminal connection

A terminal representation identifies a connection point for conductors. The terminal number and strip or assembly identifier link the schematic to physical wiring documentation. A wire number and terminal number identify different things and should not be substituted for one another.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEC / IEEE / ANSI

A distinction that matters

An electrical junction and a physical terminal are different concepts. A connection dot alone does not necessarily identify a terminal block.
