A new subsection for Electrically Safe Work Policy was added, a new informational note regarding the use of interactive web-based training (like learn.brainfiller.com) was added, operating a circuit breaker for the first time after installation is now considered a likelihood of an arc flash.
Guidance regarding risk reduction methods when the incident energy exceeds the arc rating of commercially available PPE when testing absence of voltage, New Article 360 Safety-Related Requirements for Capacitors and much more!
The 2018 Edition is here and once again, change is a constant theme. From both minor and major revisions, to new additions and major reorganizations, the 11th edition contains many changes.

The second edition of IEEE 1584 - IEEE Guide for Performing Arc Flash Hazard Calculations was Sixteen years in the making. This program provides an overview of the major changes including topics such as grounding, electrode configuration, 125 kVA transformer exception, new calculation process and more.
NFPA 70E 130.5(H) defines the minimal information for Equipment Labels (sometimes referred to as Arc Flash Labels. There are many other factors to consider such as colors, signal words, additional information, minimal information and more. This program discusses the requirements, and provides simplification strategies for arc flash labels and how to minimize the need to re-label.
