  • What is the purpose of reserving circuits in a distribution box

    What is the purpose of reserving circuits in a distribution box

    A distribution box uses MCBs, RCDs, and busbars to protect circuits, prevent shocks, and ensure safe power distribution in homes and buildings. You use a distribution box to divide electrical power into smaller circuits. Inside, you'll find parts like circuit breakers and fuses that protect the system from problems like overloads and short circuits. This enables an order and proper.
