WebSafety switches can operate (trip) with as little difference in currents between active and neutral as 30/1000th of an amp (30 milliamp). This is below the ventricular fibrillation level for adults - the level at which the normal function of your heart is disturbed. Switches that trip on 10/1000th (10 milliamp) prevent tetanus (muscular cramping).
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.
