An arc flash is defined as a hazardous explosion of energy from an electrical circuit, or a type of discharge that results from a low-impedance connection through air to ground or to another voltage phase in an electrical system. In the United States, arc flashes occur as often as five to 10 times per day. Many of these incidents result in injuries, and some are even deadly. Creating a heat blast of up to 35,000 degrees Fahrenheit, arc flash incidents can also damage equipment and interrupt business operations, leading to significant economic losses. The cause can be as simple as a rodent, a misplaced tool, humidity issues, or another element in the breaker area that compromises the electrical “spacing” between energized components. Essentially all electrical systems of voltages 200V or greater are susceptible to arc flash incidents.
