An arc flash (often called a flashover) is a type of electrical explosion or discharge that results from a connection through the air to the ground or another voltage phase in an electrical system. For example, when a wire makes contact with an earthed system. Temperatures at the source of an arc flash can reach 20,000 °C — around four times the surface of the sun.
