The excel spreadsheet files provide access to a functional Arc Flash Calculator that includes various equipment configurations (VCB, VCBB, HCB, VOA and HOA), Incident Energy and voltage ranges.
As equipment’s configuration and input fields are presented, the user will be able to key entry specific data using the proper input fields and/or pull down menus provided. All variables and constants are defined. When all variables inputs have been entered, and proper equipment configuration has been selected, the Calculator will solve the equations and the answer is returned.
See Arc Flash IE and Iarc Calculators User Manual.pdf for full instructions.

This set of data provides test results for designers and facility operators to apply in determining the arc-flash hazard distance and the incident energy to which employees could be exposed during their work on or near electrical equipment.
In order to accurately predict the response time for protective devices, the arcing current and all other variables, please refer to IEEE Std 1584-2018 IEEE Guide for Performing Arc-Flash Hazards Calculations and manufacturer’s written documentation.
The IEEE Std 1584-2018 IEEE Guide for Performing Arc-Flash Hazards Calculations includes a description of all test programs and a collection of the test data that have been used in the development of such consensus based document.
All test were conducted at high power laboratories for the purpose of developing an understanding of the electrical characteristics of arc flashes and the resultant incident energy. Such test results, as stored in this IEEE DataPort tool could be used to develop empirically based equations or to verify physical model based equations.
