An exhaust plenum forms part of a specified switchgear pressure-relief arrangement.

## What it represents

An exhaust plenum forms part of a specified switchgear pressure-relief arrangement.
Coordinate duct path, outlet zone and interfaces with the building. The GA locates the physical item; the associated schematic or equipment schedule records its electrical interfaces.
The preview is independent educational geometry and is not a manufacturer outline, fabrication drawing or verified standard graphic. Obtain the applicable model drawing from the cited official source before making a dimensional layout.

## How to read it

- Coordinate duct path, outlet zone and interfaces with the building.
- A ventilation duct cannot be assumed to fulfil an arc-exhaust function.

## Information to show or reference

- Confirm the exact equipment identity, drawing revision and installation orientation.
- Coordinate duct path, outlet zone and interfaces with the building.
- Cross-reference the terminals, cable routes and service tasks with the equipment schedule.

## Important distinction

A ventilation duct cannot be assumed to fulfil an arc-exhaust function.
