Arc Flash Hazard Analysis for NFPA 70E Compliance
time-current coordination study,. and finally, the flash-hazard analysis itself. The analysis provides, among other things, a detailed assessment of the potential energy at each point in the system that would be released in the event of an arcing fault within the equipment. This potential arc flash energy...
