Circuit interrupts preventing major shock
WebThe interrupting rating of a protective device is the fault current (generally caused by a short circuit) that the device can interrupt safely (without exploding or causing a thermal event). The amount of potential fault current to which such a device can be exposed depends on the system voltage and the resistance of the wiring upstream of the ... Webflowing through a circuit. If the current flowing into the circuit differs by a very small amount (as little as 0.006 amperes) from the returning current, the GFCI interrupts power faster than a blink of an eye to prevent a lethal dose of electricity. GFCIs are designed to operate before the electricity can affect your heartbeat. A
