Arc Flash Reduction: Defending Against Electrical Hazards
What is Arch Flash Reduction? According to NEC Article 240.87, arc energy reduction is required for circuit breakers applications of ratings 1200A and above. The requirement from the code includes proof of documentation to show the location, system, and a means of reducing the clearing time of the arc flash. Arc flash reduction as stipulated by NEC is a set of safety measures designed to minimize the risk of electrical accidents caused by arc flashes. But hold on, what’s an arc flash? Well, an arc flash is a sudden release of energy through the air, resulting from an electrical short circuit through air otherwise known as Arc Faults.
