This course is designed to equip the electrical consultant, system designer or any other professional responsible for designing or modernizing commercial and industrial electrical power distribution systems with the fundamentals of the Arc Flash Energy phenomenon. The current Safety and Arc Flash concerns can trace their history back to NFPA and IEEE activity dating back to the 70’s. Many industrial users have been incorporating concepts developed from these activities for decades. Awareness of the risks associated with electrical arc flash energy has increased since the incorporation of labeling requirements in the 2002 National Electrical Code (NFPA 70-2002) and the publication of IEEE 1584-2002. This lecture is based upon NFPA-70E-2018 ‘Electrical Safety Requirements for Employee Workplaces,’ IEEE Standard 1584-2002 ‘Guide for Performing Arc-Flash Hazard Calculations,’ NFPA70-2017, ‘National Electrical Code,’ and the regulations of the Occupational Safety and Health Administration (OSHA) in the United States.
