Arc Flash Protection & Safety | Schneider Electric USAAn arc flash results from an arc fault. Arc faults are caused by electricity discharging between two or more conductors that are improperly connected, such as frayed wires. Dust or moisture can also cause arcing between conductors, which explains why high-voltage power lines will glow in foggy weather. Use this Arc Flash library to learn :
