Weíre all human and we all make mistakes. But mistakes in the electrical field can prove costly. Codes and standards work together to reduce mistakes and save lives, which is what makes NEC (National Electrical Code) Section 240.87, Incident Energy Reduction, so significant.
It was introduced to the NEC in 2011 as the first requirement focused on incident energy reduction since Ground Fault Protection of Equipment (GFPE) entered the NEC in 1971. Section 240.87 provides electricians and maintenance workers the overcurrent protective device technologies necessary to reduce distribution system energy. This mitigates damage to electrical equipment and, more importantly, reduces loss of life and injury from arc flash events.
