An Residual Current Device also known as an RCCB (Residual Current Circuit Breaker), is a crucial safety device designed to protect against electrical shock and fire hazards caused by earth faults. It monitors the balance of electrical current flowing through live and neutral conductors. If it detects an imbalance, indicating a leakage current that could potentially be dangerous, the RCD rapidly disconnects the circuit to prevent harm. This swift reaction minimizes the risk of electric shocks and prevents damage to electrical systems. RCDs are essential in both residential and commercial electrical installations, enhancing overall safety and compliance with electrical standards.
