## Symbol convention

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

Plan mark for a flush floor box containing power and often data outlets in open-plan floors.

## In plain English

### What does Floor box outlet mean?

A floor box houses socket outlets and frequently data outlets below a hinged lid flush with the finished floor. Plans draw a square around the outlet mark, sometimes with a diagonal or the letters FB, and list the box contents in a schedule because each box can hold several accessory types.

### A simple example

Floor boxes are used in open offices, meeting rooms and lobbies where furniture is away from walls. They require coordination with the floor finish, raised-floor tiles or screed thickness, so the symbol is often cross-referenced to an architectural floor setting-out plan.

### What the drawings help you do

The square does not tell you how many outlets the box contains. Read the floor box schedule for power, data and AV contents and the circuit allocation of each power outlet.

### This particular reference

Plan mark for a flush floor box containing power and often data outlets in open-plan floors. A multiple socket outlet on a wall shows a gang count; a floor box is an enclosure whose contents are scheduled separately.

### Terms

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

## How to read it

- The square outline around the outlet is the usual floor indication.
- Expect a schedule listing box contents.

## Information to show or reference

- Reference the floor box schedule entry.
- Coordinate setting out with the floor plan grid.
- Tag power circuits and data outlet numbers.

## Important distinction

A multiple socket outlet on a wall shows a gang count; a floor box is an enclosure whose contents are scheduled separately.

## Facts

- Mounting: Flush in floor screed or raised access floor
- Contents: Power, data and AV modules per schedule
- Exact standard graphic: Not reproduced here; confirm the form against IEC 60617 and the project legend
