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

JMP

IEEE / ANSI

ANSI/IEEE terminal jumper symbol

US-practice schematics show jumpers between terminals as a short line or curved strap linking terminal circles, often with a JMP designation. It is common on relay panel terminal strips where common supplies or returns are distributed across several terminals.

Drawing use: Schematic
Application: Connections & wiring
Reference family: IEEE / ANSI
Form evidence: Terminal jumper form. Independent illustration in IEEE drafting context; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A terminal jumper ties adjacent terminals; a wire splice joins conductors without terminals.

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.
