This standard provides guidance and checklists for the collection of required data for performing an arc-flash hazard calculation study in accordance with the process defined in IEEE 1584-2018 and IEEE 1584.1-2022 for systems operating at three-phase 50/60 Hz alternating current (AC) 1000 V and below. This standard does not include collection of data required for performing other system studies, such as a short-circuit study and overcurrent protective device coordination study.
