What Is Arc Fault Detection (AFDD)?
Arc fault detection (AFDD) is a safety technology that detects dangerous electrical arc faults caused by damaged cables or loose connections. It helps prevent electrical fires by disconnecting power when a fault is detected.
Why Arc Fault Detection Matters in EV Infrastructure
EV charging installations involve high electrical loads. AFDD enhances fire safety by identifying arc faults that traditional protection devices may miss.
