    Each circuit uses a residual current device RCD 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. RCDs are invaluable safety devices and are essential for anyone using or. A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral. An RCD, which stands for Residual Current Device, is also known as a Residual Current Breaker (RCB) or Residual Current Circuit Breaker (RCCB). The primary function of an RCD is to monitor the electrical current. Safely disconnect the power in the event of a fault with residual current devices (RCDs) — essential in building electrical distribution boards. Here you will learn how to connect RCDs, what to do if the fuse blows, and what types of RCDs are available.
