How does a circuit breaker work physics
WebFeb 24, 2012 · An Earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations (both residential and commercial) with high Earth impedance to prevent electric shocks. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. WebNov 26, 2024 · The circuit breaker, the wire and even the wire insulation are all designed to work as a system—and that system has limits. Try to push more current through a circuit than it’s designed for and things start happening ( Fig. B ). Wires heat up under the burden of carrying the excess current.
