WebProtective devices capable of responding to overloads and short circuit, such as circuit breakers, have been available for a number of years. Newer technologies now provide enhanced protection from arcing or ground-faults, which may prevent fires or 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 ...
