  • Explanation of the final-level electrical distribution box

    Explanation of the final-level electrical distribution box

    A final distribution board (often called FDB, DB, breaker box, or fuse box) is the last stage of low-voltage power distribution before electricity reaches end loads such as lights, sockets, small motors, and terminal equipment. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV. Our distribution boards guide explains what they are, their uses and types, and how to connect distribution boards. But what exactly is a power distribution box, and why is it so essential in our daily lives? The DB panel board controls the flow of electricity.
