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.

JUNCTION

Symbols

Conductor connection junction

A junction indication marks a documented electrical connection between conductor branches. The junction is a drawing connectivity statement: the branches belong to one connected electrical network at that point. It is different from a hardware splice which may have its own material and installation record.

Drawing use: Schematic
Application: Connections & wiring
Reference family: Manufacturer

A distinction that matters

A crossing line is not necessarily a connected conductor.

Terminal

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.
