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.
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.
Definition from ChatGPT:
Electrical room:
An electrical room is a designated space within a building or facility that houses electrical equipment, such as switchgear, distribution boards, transformers, and other components necessary for the distribution of electricity throughout the building. It is a controlled environment designed to ensure the safe operation and maintenance of electrical systems.
