A Power Distribution Board (PDB) is an electrical device that distributes electrical power to various circuits within a system. It serves as a central hub where incoming power is split into multiple outgoing circuits, ensuring that each component receives the appropriate voltage and current. PDBs are commonly used in residential, commercial, and industrial settings to manage electrical loads safely and efficiently. These boards typically include circuit breakers or fuses to protect against overloads and short circuits. By organizing and controlling the flow of electricity, PDBs help maintain system stability and prevent electrical hazards, making them essential for safe electrical installations in buildings and machinery.
