An Electrical Distribution Board (often called a DB) is a crucial component in electrical systems, responsible for distributing electricity from a main supply to various circuits within a building. It houses circuit breakers or fuses that protect electrical circuits from overloads and short circuits, ensuring safety and reliability in electrical distribution. Typically mounted on walls, distribution boards come in various sizes and configurations, depending on the building's electrical needs. They are essential for managing power supply in residential, commercial, and industrial settings, helping to maintain efficient and safe electrical operations throughout the premises.
