Webv. t. e. 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 installations instead use ... WebA grounding resistance tester also called an earth tester is a soil resistance measuring instrument.
