Video of Arc Flash DemonstrationWhat does an arc flash explosion look like? A 480v 3-phrase demonstration of an arc flash was set up in a laboratory and video taped. An arc flash is usually caused by something, most commonly dirt or debris, causing a short circuit. For example, here is a report of an arc flash incident caused by a tool that fell into a breaker panel.
In this demonstration the arc flash was intentionally started by placing wires across the three copper bus bars. This created the short circuit normally caused by dirt or debris. Power (480v) was then applied to the bus bars for about 1 second.
