Arc flash temperatures can reach or exceed  at the arc terminals. The massive energy released in the fault rapidly vaporizes the metal conductors involved, blasting molten metal and expanding plasma outward with extraordinary force. A typical arc flash incident can be inconsequential but could conceivably easily produce a more severe explosion (see calculation below).
Arc flash temperatures can reach or exceed  at the arc terminals. The significant energy released during the fault vaporizes the metal conductors, expelling molten metal and expanding plasma outward with considerable force. A typical arc flash incident might be minor but could potentially lead to a more severe explosion (see calculation below).
