Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

IEEE / ANSI

ANSI/IEEE multi-conductor cable symbol

US-practice schematics group conductors of one cable with an enclosing outline, a bracket or an oval drawn across the conductor lines, usually with the cable number beside it. It lets the reader see which wires travel together between enclosures.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEEE / ANSI
Form evidence: Multi-conductor cable grouping. Independent illustration in IEEE drafting context; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A cable grouping shows shared jacket only; a shielded cable form adds a conductive shield.

IEC

Conductors within one cable

On multi-line schematics each core is drawn as a separate line, which hides the fact that several of them share one sheath. A grouping outline drawn across those lines tells the reader they are cores of one cable. It is typically paired with a cable tag so that the cores can be traced to the cable schedule.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEC
Form evidence: Cable core grouping form. Independent IEC-context illustration; not certified IEC geometry.

A distinction that matters

A grouping outline shows shared sheath only; a screen outline shows a conductive shield around the cores.
