Which mechanism causes arc flash events in electrical panels?

💡 Explanation

Arc flash occurs due to accelerated electromagnetic induction of plasma, forming a conductive path, because ionized air markedly lowers resistance, allowing enormous current flow; therefore, arc flashes propagate, rather than being contained by standard fuse actions in overload.
