An electrical room is a technical room or space in a building dedicated to electrical equipment. Its size is usually proportional to the size of the building; large buildings may have a main electrical room and subsidiary electrical rooms. Electrical equipment may be for power distribution equipment, or for communications equipment.[1]
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.
