The Arc Flash Calculator will calculate hazardous arc flash levels (incident energy). This calculator will analyze the required Personal Protection Equipment (PPE), safe working distance, and arc flash hazard zones for arc flash faults when working on or near energized equipment. This calculator is based on the IEEE 1584-2002 standard. Reference the 2015 NFPA 70E®: Standard for Electrical Safety in the Workplace® for a more complete reference for Arc Flash Hazard calculations and safety.
Enter the information below to calculate arc flash incident energy and arc flash protection boundary.
Refer to the Arc Flash Tables for Hazard Risk Category, and appropriate Personal Protection Equipment (PPE) based on arc flash incident energy levels.
