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.

### This particular reference

IEEE-oriented jumper drawn between adjacent terminals to show they are strapped together. A terminal jumper ties adjacent terminals; a wire splice joins conductors without terminals.

### Terms

- Coil: A wound conductor that can produce a magnetic field when energised.
- Terminal: An identified point where a conductor connects.
- Schematic: A drawing showing function and connections rather than physical appearance.

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.

## 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.

## Important distinction

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