Application of IEEE 1584 to IEC Equipment

IEEE 1584 provides models and an analytical process to enable the calculation of the predicted incident thermal energy and the arc-flash boundary. The Guide provides typical dimensions and working distances for different types of electrical distribution equipment where arc-flash hazards exist. However, this typical data is generally focused on equipment manufactured to ANSI/NEMA standards. This paper will highlight the differences when applying the IEEE 1584 models and analytical processes to equipment manufactured to IEC standards.
