Unlike standard circuit breakers that only respond to overcurrent (too much amperage), AFDDs analyze the electrical waveform to identify the high-frequency &#8220;signature&#8221; of arcing\u2014which can occur at current levels too low to trip a regular breaker. Think of it this way: a circuit breaker is like a flow meter that shuts off when volume exceeds capacity; an AFDD is like a quality analyzer that detects contamination even at normal flow rates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. \uc774\ubbf8 RCBO \ubcf4\ud638\ub97c \ubc1b\uace0 \uc788\ub294\ub370 AFDD\uac00 \uaf2d \ud544\uc694\ud55c\uac00\uc694?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. While RCBOs (Residual Current Circuit Breakers with Overcurrent protection) provide excellent protection against ground faults, overloads, and short circuits, they offer limited protection against series and parallel arc faults. An arc fault can occur entirely within the circuit&#8217;s normal current path, meaning no ground fault current flows to trigger the RCBO. AFDDs detect these dangerous arcs by analyzing waveform characteristics, not just current magnitude or ground leakage. For comprehensive protection, modern installations should include both technologies\u2014either as separate devices or as combination AFDD+RCBO units now available from major manufacturers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3.
