TB BRIDGE
Terminal jumper bridge
A terminal bridge intentionally connects specified terminal points to a common potential.

ANSI/IEEE terminal jumper symbol
IEEE-oriented jumper drawn between adjacent terminals to show they are strapped together.
In plain English
What does ANSI/IEEE terminal jumper mean?
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.
A simple example
This illustration is an independent explanation rather than the IEEE graphic. A jumper can be a plug-in bridge, a wire link or a screwed strap, and the symbol does not distinguish them. Jumpers that must be removed for testing should be identified as such.
What the drawings help you do
Check whether the jumper is removed during testing. Identify the physical jumper type. A terminal jumper ties adjacent terminals; a wire splice joins conductors without terminals.

How to read it
- Check whether the jumper is removed during testing.
- Identify the physical jumper type.
Information to show or reference
- Show every jumper on the terminal plan.
- Mark test-removable jumpers.
- Keep the jumper current within terminal rating.
A distinction that matters
A terminal jumper ties adjacent terminals; a wire splice joins conductors without terminals.
