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

TB BRIDGE

Symbols

Terminal jumper bridge

A terminal bridge intentionally connects specified terminal points to a common potential. The drawing needs the actual bridged positions rather than an undifferentiated line across an entire terminal strip.

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

A distinction that matters

A bridge is an intentional common connection; close physical spacing does not establish electrical continuity.

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.
