IEEE 1584 is the IEEE Guide to Arc Flash Calculations. First published in 2004 this document has been instrumental in defining the hazard that workers may encounter when working around live electrical equipment. This document has provided valuable information for countless electrical system design decision, equipment purchase decision and decision impacting the safety or personnel. This document is instrumental to the proper application of NFPA70E and complying to OSHA guidelines in many cases. The IEEE and the NFPA, several years ago, initiated a project to better understand arcing phenomena and to, potentially, develop a more accurate model. After almost 2000 high current tests the model will soon be published. And the changes will be substantial. This short presentation will describe the new model, the parameters that go into the model and will review some of the practical differences the new model may make for your arc flash study, maintenance practices, your design decisions and your perception of the hazard presented by energized conductors.
