Understanding Ground Fault and Leakage Current Protection
Web28 sep. 2024 · The life expectancy of a GFCI outlet is between 15 and 25 years, and a GFCI breaker can last up to 30 years. However, certain conditions may reduce the life … Web11 jun. 2013 · A GFCI or EGFPD contains its own interrupting device (a relay, contactor, or circuit breaker) to interrupt power, and it interrupts power much more quickly. Per UL 943C, a GFCI must open the circuit to interrupt power in less than 20 ms for higher currents. This time is fast enough to prevent shock injury. A Class A GFCI trips when the current to ground has a value in the range of 4mA to 6 mA (reference UL 943). In other words, it should not trip at less than 4mA. The trip time must be <= 25ms. They will not trip at 60uA or even 1mA because that would cause nuisance tripping from capacitive coupling or … Meer weergeven I originally asked "Minimum current level to trip a GFCI"?
