## Symbol convention

Convention: IEC
Form: Lighting track
IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

Plan mark for a lighting track that carries adapters for movable luminaires, drawn as a double line.

## In plain English

### What does Lighting track plan mark mean?

Lighting tracks are drawn as a double line or a line with regular cross ticks along the track run, with spotlights attached as separate symbols. The track is fed at one end or mid-point, and multi-circuit tracks allow luminaires to be assigned to different circuits.

### A simple example

The plan shows track length and feed point, which the installer needs to order sections and end caps. Multi-circuit tracks are tagged with the number of circuits. The track symbol does not show how many luminaires will be clipped on in use. Loading is planned from the schedule.

### What the drawings help you do

Find the feed point. Read circuit count for multi-circuit track. A linear luminaire emits light along its length; a track only carries adapters for separate luminaires.

### This particular reference

Plan mark for a lighting track that carries adapters for movable luminaires, drawn as a double line. A linear luminaire emits light along its length; a track only carries adapters for separate luminaires.

### Terms

- Schematic: A drawing showing function and connections rather than physical appearance.

## How to read it

- Find the feed point.
- Read circuit count for multi-circuit track.

## Information to show or reference

- State track length.
- State circuits.
- Show feed point.

## Important distinction

A linear luminaire emits light along its length; a track only carries adapters for separate luminaires.

## Facts

- Graphic form: Double line with ticks
- Fed from: End or centre feed point
- Exact standard graphic: Not reproduced here; confirm the form against IEC 60617 and the project legend
