IEEE-oriented hop or loop drawn where one conductor passes over another without connecting.

## In plain English

### What does ANSI/IEEE crossing conductor hop mean?

Older ANSI-style schematics often draw a small semicircular hop where one conductor crosses another, removing any doubt that the two are unconnected. Many CAD packages offer the hop, a gap or a plain crossing as display options, and the choice is set per drawing set.

### A simple example

The hop carries no physical meaning; it is a reading aid. This illustration is an independent explanation of the convention rather than a reproduction of the IEEE graphic. Where a drawing set mixes hops and plain crossings, check the legend rather than assuming that plain crossings are connected.

### What the drawings help you do

Treat the hop as no connection. Check whether the drawing set also uses plain crossings. A hop is an unconnected crossing; a junction dot is a connection.

### This particular reference

IEEE-oriented hop or loop drawn where one conductor passes over another without connecting. A hop is an unconnected crossing; a junction dot is a connection.

### Terms

- Normally open / normally closed: The contact state in the normal condition defined for the drawing.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Older ANSI-style schematics often draw a small semicircular hop where one conductor crosses another, removing any doubt that the two are unconnected. Many CAD packages offer the hop, a gap or a plain crossing as display options, and the choice is set per drawing set.
The hop carries no physical meaning; it is a reading aid. This illustration is an independent explanation of the convention rather than a reproduction of the IEEE graphic. Where a drawing set mixes hops and plain crossings, check the legend rather than assuming that plain crossings are connected.

## How to read it

- Treat the hop as no connection.
- Check whether the drawing set also uses plain crossings.

## Information to show or reference

- Use one crossing display style per drawing set.
- Never place a junction dot on a hop.
- State the crossing convention in the legend.

## Important distinction

A hop is an unconnected crossing; a junction dot is a connection.
