AFCI's detect arcing faults (an unintentional arcing condition in a circuit) that standard circuit breakers are unable to detect. The device is intended to mitigate the effects of arcing faults by functioning to de-energize the circuit when an arcfault is detected.
|Long time and instantaneous|
|Detects all three possible types of arc faults - line to ground, line to neutral and series|
|14 to 8 AWG copper, 12 to 8 AWG aluminum|
