Unlike a conventional circuit breaker, which detects overloads and short circuits, an arc fault circuit interrupter (AFCI) uses advanced electronic technology to sense different arcing conditions.

Circuit breakers, despite any techy magic happening beneath the surface, should be the most predictable things in the world. If they encounter a ground fault or an overcurrent/overload situation (or ...

Arc-Fault Circuit-Interrupters are relatively new electrical safety devices that first appeared in the 1999 National Electric Code. AFCI devices look very similar to GFCI devices, in that they have a ...

Although flawed in its execution, the addition of AFCIs to the 2002 Code highlights the importance of arc-fault protection. Circuit breakers and fuses are effective in preventing fires caused by a ...
