⚡ NFPA 70E / IEEE 1584 Arc Flash Boundary, Incident Energy Cal/cm² & PPE 1-4

IEEE 1584 Arc Flash Incident Energy & PPE Calculator

Calculate electrical arc flash incident energy and boundary distances under IEEE 1584 & NFPA 70E: calculate incident energy (Cal/cm² at 18" working distance based on arcing fault current kA and clearing time seconds), required arc-rated PPE Category (8 Cal, 25 Cal, 40 Cal, or >40 Cal dangerous blast), and electrical safety audit margins.
