    Residual Current Circuit Breakers (RCCBs), also known as Residual Current Devices (RCDs), play an essential role in modern electrical safety. Their primary function is to protect against electrical shock and fire hazards by detecting leakage currents and disconnecting the circuit before damage occurs. This article delves into the workings, importance, and applications of RCCBs, highlighting why they are a critical component in electrical systems.

    How RCCBs Work

RCCB

    An RCCB operates on the principle of detecting imbalance between live and neutral wires. In a typical electrical system, the current flowing through the live wire should be equal to the current flowing back through the neutral wire. If there is a leakage current due to insulation failure or a person coming into contact with a live conductor, the RCCB senses this imbalance. When the detected imbalance exceeds a preset threshold (usually 30mA for residential systems), the RCCB rapidly disconnects the circuit, thereby preventing potential harm or fire.
