A lot 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. READ MORE

One of the first steps in performing an arc flash hazard calculation study is to request the short-circuit data from the electric utility company. This information is critical because it defines the magnitude of current that could flow from the utility and is used as a starting point for arc flash calculations. READ MORE

OUCH! I can’t believe I just did that. While trimming the hedge at home one afternoon, I moved the orange extension cord around one of the bushes. Simple enough—being a very safety conscious person, I wanted to ensure I did not accidently cut it. As I grabbed the cord, I felt an unexpected surprise. The painful buzz in my hand said it all. I had just received an electric shock. READ MORE

A few months ago, I was driving home from the Los Angeles area and suddenly found myself surrounded by thousands of wind turbines lining both sides of Interstate 10. Even though I have made this trip many times, I am still in awe at the scale of it all. READ MORE

Plato, the Greek philosopher, had it right almost 2,500 years ago. He is widely credited for the quote, “Necessity is the mother of invention.” When it comes to arc flashes, many creative methods have been developed out of necessity to reduce or eliminate these potentially deadly hazards. READ MORE
