WebJul 16, 2000 · An arc looks much like a resistor element in a circuit and will frequently have a constant voltage drop of between 20 and 30 volts across it. Also, notice that “shoulders” appear on the current traces around the current zero locations. The arc ignites only after sufficient voltage across the gap returns following a current zero. WebAn arc-fault circuit interrupter (AFCI) is a circuit breaker* located in your electrical panel that serves the functions of a normal breaker but also senses hazardous arcing on its circuit and will trip off for this. It can be identified by the special colored test-button near its handle.
