Flyer for Marcelo’s IEEE 1584 Update

Abstract: IEEE 1584 has been the definitive guide for Arc Flash calculations since its original publication in 2002. Today its impact on the electrical equipment industry would be difficult to exaggerate. The guide has been republished with significant changes to the model used for predicting incident energy, arcing current and the 1.2 calorie arc flash boundary. Rather than an evolutionary change, the new edition of this important IEEE guide is a revolutionary change in how we understand the science of estimating the severity of the arc flash hazard. Consultants, users and workers need to understand the new model and what it says about the hazard posed by exposure to live electrical equipment. Many organizations have invested in arc flash studies over recent years whose results are now questionable. However, before the study can be updated tasks may need to be accomplished. The question may be, is the previously selected
PPE still good enough? Marcelo will provide a method with which to answer this question based on a method described in an IEEE paper presented earlier this year at the IEEE Electrical Safety Workshop, “CONSIDERATIONS FOR ADAPTING IEEE 1584-2002 ARC FLASH STUDY RESULTS TO A POST IEEE 1584-2018 RISK ASSESSMENT” By M.E. Valdes & H.L. Floyd.
