    Abstract

    NFPA 70E and CSA Z462 require a Qualified Person to document a work task's arc flash risk assessment. Single-phase electrical equipment would currently be identified as not able to sustain an abnormal arcing fault. IEEE 1584 - 2018 documents the standard method for calculating arc flash incident energy at an assumed working distance and the arc flash boundary distance, for 208VAC to 15kVAC three-phase electrical equipment. While IEEE 1584 covers three-phase systems in detail, the 2002 and 2018 editions do not provide modeling methods for single-phase systems. Single-phase and split phase AC power are the standard for residential and light commercial distribution around the world, and single-phase electrical equipment is common in industry. This paper describes single-phase arc flash experimental work conducted in 2020 as part of doctoral study and underpinning a dissertation. The principal investigator's goal was to improve confidence in arc flash & electric shock equipment labeling practices in support of his role as an industrial plant chief electrical engineer. The experimental hypothesis was: there would be some available system energy threshold below which arc flash incident energy would be low (less than 1.2 cal/cm2).
