Electrical room
An electrical room is a
Electrical rooms typically house the following equipment:
- Electric switchboards
- Distribution boards
- Circuit breakers and disconnects
- Motor control centers
- Transformers
- Busbars
- Electricity meters
- Backup batteries in a Battery room
- Fire alarm control panels
- Distribution frames
In large building complexes, the primary electrical room may house an indoor electrical substation.
Construction features
The construction features of an electrical room vary depending on the scope of the equipment to be installed. Floors may be reinforced to support heavy transformers and switchgear. Walls and ceilings may have to support a heavy
A large electrical room may have extensive provisions for grounding (earthing) and bonding enclosures of electrical equipment to prevent
Regulations
Layout details and construction of electrical rooms will be controlled by local
In industrial buildings that handle flammable gases or liquids, or combustible dusts, special electrical rooms may be prepared that have ventilation and other measures to prevent an explosion hazard that would otherwise exist with electrical equipment in hazardous areas. For large installations, it may be less costly overall to use a special room than to install a large number of devices that are resistant to the hazardous conditions. Similarly, in wet or corrosive environments, electrical equipment may be separated in a room that can be protected from the atmospheric conditions.
Building code and electrical code regulations will dictate minimal working space around equipment to allow safe access during maintenance. Practical design of an electrical room will consider layout of the initial equipment and allow for additions over the economic life of the facility.
