An MDP (Main Distribution Panel) is the primary electrical distribution point that receives power from the utility service entrance and distributes it to downstream sub-panels, branch circuits, and loads. MDPs include switchboards, switchgear, and service entrance equipment rated from 400A to 4000A. They provide centralized overcurrent protection and load management for commercial, industrial, and utility facilities.
