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 terminal with wire number symbol

The publisher's IEEE terminal preview lists a round terminal form that shows the wire number at the terminal. It is used where the wire identity is more useful to the reader than the terminal position, for example on field wiring sheets where technicians trace wires by number.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Round with Wire Number terminal. Autodesk publishes this block under IEEE Symbol Preview: Terminals. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

This form shows the wire number; the ANSI numbered terminal form shows the terminal number.

Terminal carrying wire identification

This terminal representation carries the associated wire identifier at the connection point.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEC / Manufacturer
Form evidence: Terminal carrying wire identification. Autodesk IEC-60617 Symbol Preview — Terminal numbering forms; vendor family reference, not certified IEC geometry or database identifier.

A distinction that matters

A wire number and a terminal number should not be substituted for each other.
