Voltage earth leakage circuit breakers (ELCBs) are safety devices designed to protect electrical circuits from faults that could lead to electric shocks or fires. They monitor the flow of electricity and detect any imbalance between the live and neutral wires, which may indicate a leakage of current to the ground. When an imbalance is detected, the ELCB quickly disconnects the power supply, preventing potential hazards. These devices are essential in residential and commercial settings, ensuring the safety of people and property by minimizing the risk of electrical accidents.
