Working around electrical equipment, it’s imperative to understand the potential hazard of arc flashes, what causes them, and how to prevent serious damage to people and assets. When electrical current passes through the air from one point to another, the resulting arc flash can reach temperatures up to 35,000° F. An arc flash is the light, concussive energy, and heat produced as part of an arc fault, a type of electrical discharge that results from a connection from phase to phase, or phase to ground.
