Current earth leakage circuit breakers, often referred to as ELCBs, are safety devices designed to prevent electric shocks and electrical fires. They work by detecting any imbalance between the live and neutral wires in an electrical circuit. If a fault occurs, such as a person touching a live wire, the ELCB quickly cuts off the electricity supply, reducing the risk of injury. These devices are essential in residential and commercial buildings, providing an extra layer of protection for users. Modern ELCBs are sensitive and can detect small leakage currents, ensuring that any potential hazards are addressed promptly. Regular testing and maintenance of these devices are crucial for optimal performance.
