Arc Flash as it Relates to AC Drives

An arc flash (or arc blast) is a type of electrical explosion that results from a low impedance connection to ground or another voltage phase in an electrical system.

Even without electrocution, death or dismemberment may occur through an intense arc blast, up to 35,000 F deg, and force up to 2100 psi from the intense heat rapidly expanding the air, copper & particles creating a shockwave blast.  Droplets of molten metal and shrapnel can penetrate the body.
