MDB & SDB Panel
Main Distribution Board (MDB)
A Main Distribution Board (MDB) is the central electrical panel that distributes power from the incoming supply to various branch circuits within a building or facility. It houses protective devices such as circuit breakers, fuses, and switches to ensure safe and efficient power distribution. The MDB is typically installed directly after the main power source (transformer or utility supply) and is responsible for monitoring, controlling, and protecting the electrical system. It includes components for load management, fault isolation, and system protection. MDBs are widely used in residential, commercial, and industrial installations to organize and manage electrical power distribution efficiently and safely.
Sub Distribution Board (SDB)
A Sub Distribution Board (SDB) is a secondary electrical panel that receives power from the Main Distribution Board (MDB) and further distributes it to specific areas or loads within a building. It helps manage and control electrical supply to localized circuits, improving system organization, safety, and efficiency. The SDB contains protective devices such as miniature circuit breakers (MCBs), residual current devices (RCDs), and isolators to safeguard individual circuits from overloads and faults. Commonly used in large residential, commercial, and industrial settings, SDBs allow for easier maintenance, localized control, and reduced load on the main distribution board, enhancing overall power distribution reliability.
