In the dynamic landscape of BSNL's power infrastructure, Lighting Distribution Boards (LDBs) emerge as vital components, responsible for the organized and efficient distribution of electrical power to lighting systems.

Components:

Main Switch or Isolator: The main switch or isolator serves as the primary control device, allowing for the manual disconnection of power to the entire lighting distribution board when needed.
Miniature Circuit Breakers (MCBs) or Fuses: MCBs or fuses provide overcurrent protection for individual lighting circuits. They automatically disconnect the circuit in case of overloads or short circuits.
Busbars: Busbars are conductive strips that distribute electrical power from the main switch to individual MCBs. They provide a common connection point for the various lighting circuits.
Indicators and Controls: Indicators, such as LED lights, display the status of individual circuits. Some LDBs may include controls for manual operation and testing.
Enclosure: The enclosure houses all the components of the LDB, providing protection against environmental factors and ensuring the safety of personnel.
