A distribution box (DB box) is a metal or plastic enclosure that serves as the central hub for an electrical system, receiving power from the main supply and distributing it to multiple subsidiary circuits throughout a building. It contains safety devices like circuit breakers, fuses, and bus bars that protect the system from overloads and short circuits, ensuring electricity is delivered safely and efficiently to various outlets and equipment.
-
Central Hub:
It acts as the central point where electrical power is divided and directed to different areas or devices within a building.
-
Protection:
The box houses circuit breakers, fuses, or other protective devices designed to trip and cut off power in the event of an overload or short circuit, preventing damage.
-
Distribution:
It distributes power from the main supply into smaller, manageable circuits, allowing for organized control and management of electricity.
-
Components:
Common components found inside include circuit breakers, fuses, bus bars (for connections), and sometimes meters or surge protection devices.
- Distribution boxes are typically found in utility rooms, garages, basements, or other accessible areas of a building.
