A Main Distribution Board (MDB) panel is a secondary-level electrical distribution assembly that receives power from a main switchboard or PCC panel and distributes it to various sub-circuits, lighting loads, small motors, and utility feeders within a facility. It houses MCBs, MCCBs, and other protective devices organized in a compact enclosure, ensuring safe and reliable distribution of electrical power to end-use equipment. PDB panels are commonly used in industrial plants, commercial buildings, and infrastructure projects where power needs to be channelled efficiently from a central source to multiple points of consumption.
