Alot has happened since 2002 when IEEE 1584-IEEE Guide for Arc-Flash Hazard Calculations was first published by the Institute of Electrical and Electronics Engineers. The development of this landmark document included conducting more than 300 arc flash tests, which were used to create the empirically derived equations. Applicable for three-phase calculations and voltages ranging from 208 volts (V) to 15,000V, four main calculation methods are the backbone of this standard. They include the following: 1.Arcing short-circuit current-systems less than 1,000V 2.Arcing short-circuit current-systems from 1,000 to 15,000V 3.Incident energy 4.Flash hazard boundary (known today as the arc flash boundary).
