摘要

The following information will be presented: Introduction, and the rules: NFPA 70E and the application of IEEE 1584, the standard that provides techniques to apply in determining arc-flash incident energies. Incident energy calculations for like systems of different voltages. Comparison of two 3000 kVA systems with 1500 kVA of K-13 inrush. -480 Volt Secondary -4160 Volt Secondary Examples of real systems that are HRC Dangerous. What's the solution? What will it take for Safety to take precedence over business-as-usual?
