IEEE 1584 standard updates

On November 30 2018, IEEE published updates to IEEE 1584, IEEE Guide for Performing Arc-Flash Hazard Calculations. The guide, updated for the first time since 2002, provides a new mathematical model to determine arc flash hazard incident energies and boundaries. The new 2018 guide is based on more than 1800 laboratory tests, compared to just 300 tests for the 2002 model. The result is a new mathematical model and calculation procedure that is more comprehensive, accurate and complex than before. 

Three main changes effect how arc flash studies should be performed.
