A Miniature Circuit Breaker (MCB) distribution board is a crucial component of electrical systems, commonly found in residential, commercial, and industrial settings. It serves as a central point for distributing electrical power from the main supply to various circuits within a building. MCBs are installed within the distribution board to protect individual circuits from overcurrents and short circuits. These devices automatically trip and disconnect the circuit when an abnormal condition occurs, preventing damage to appliances, wiring, and ensuring safety.
The distribution board typically consists of multiple MCBs arranged in rows or columns, each connected to different circuits such as lighting, power sockets, or specialized equipment. Additionally, the distribution board may include other components such as busbars, neutral bars, and earth bars for efficient wiring and grounding.
