An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent … See more The main purpose of Earth leakage protectors is to prevent injury to humans and animals due to electric shock. See more This is a category of devices, which are used to protect instruments, circuits and operators, while Earth leakage. Early ELCBs were voltage operated devices (VO-ELCB), detecting a voltage rise between installation metalwork, and an external electrode. … See more There are two types of Earth-leakage circuit breaker: • voltage operated (referred as ELCB in this article) and, • current operated (referred to as RCCB in this article). Voltage-operated … See more An ELCB is a specialised type of latching relay that has a building's incoming mains power connected through its switching contacts so that the ELCB disconnects the power when earth leakage is detected.
