Residual-Current Circuit Breaker (RCCB)

A Residual-Current Circuit Breaker (RCCB) is a safety device designed to protect people from electric shocks and prevent electrical fires. It detects any imbalance between the live and neutral wires, indicating that current may be leaking to the ground, possibly through a person or faulty wiring. When such a leak is detected, the RCCB quickly shuts off power, reducing the risk of injury or fire. It does not control the appliance’s operation but works as a sensitive safety switch to monitor electrical current flow and ensure safety in residential and commercial circuits.
