What is NEC 240.87? NEC 240.87 is a code section in the National Electrical Code (NEC) that requires arc energy reduction methods for circuit breakers rated at 1200 amps or higher. Arc energy is the amount of heat and light produced by an electrical arc fault, which can cause severe damage to equipment and personnel. Arc energy reduction methods are designed to reduce the duration and intensity of an arc fault, thereby minimizing the potential hazards. Why is NEC 240.87 important?
