Distribution boards in the Power Supply category are critical electrical components that function as the main hubs for electrical power distribution within a building or facility. They house protective circuit breakers or fuses and serve as the central point where the incoming power supply is divided into separate circuits. Each circuit within a distribution board typically controls power to a different area or type of device, ensuring that electricity is distributed efficiently and safely throughout the structure. Distribution boards are essential for managing electrical loads and protecting wiring systems from overload or faults.
