Application of IEEE 1584-2018 to International Electrotechnical Commission Equipment: Developing Dimensions for Use During Early Project Stages

IEEE Standard 1584-2018 provides models and an analytical process to enable the calculation of the predicted incident thermal energy and the arc-flash boundary. The guide includes the dimensions and working distances for the different types of electrical equipment evaluated in the arc-flash incident energy (IE) tests used to create the model. The equipment used in these tests were manufactured to ANSI/National Electrical Manufacturers Association (NEMA) standards. This article highlights the differences when applying the IEEE Standard 1584-2018 models and analytical processes to equipment manufactured to International Electrotechnical Commission (IEC) standards.
