  1. Does your arc flash calculater use the IEEE 1584 – 2002 or IEEE – 2018 calculations? I work in the power system analysis consulting industry and this app could come in handy during data collection at facilities with no arc flash labels.

    1. The calculations are based off the methodology presented in 2018 NFPA 70E. Their methodology is based off the revised IEEE 1584 2002.
