The first step in conducting an arc flash study is to obtain the data necessary to accurately represent the electrical system. Equations defined by IEEE 1584–IEEE Guide for Performing Arc Flash Hazard Calculations are at the heart of most studies and require a lot of data.  READ MORE

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

The surface area of the earth is approximately 197 million square miles, and IEEE 1584—IEEE Guide for Performing Arc-Flash Hazard Calculations has been covering more of it every day since it was first published almost 11 years ago. READ MORE

Without warning, smoke rolled out from under the tires as they squealed against the pavement with the brakes locked up. The big truck seemed to come from nowhere. It felt like an eternity; although it was really only a matter of seconds, then … CRASH! READ MORE

After having consultants crawl all over the place, asking questions and gathering mounds of data, the arc flash study for your facility is finally done. Now the big question: with endless calculations based on IEEE 1584, IEEE Guide for Performing Arc-Flash Hazard Calculations, what do the numbers mean? More important, how do you incorporate the results into your electrical safety program? READ MORE

“Kill the Circuit.” This phrase is a colorful way of saying de-energize the circuit. Easy enough­—just open a switch or other protective device and the circuit is “dead.” It should then be safe to work on, right? Wrong! Simply opening a switch does not guarantee the circuit is de-energized. Really? What could go wrong?  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

It happened once again! In one of my training programs, someone asked the all-too-familiar question, “What color should arc flash warning labels be?” It’s no wonder people are confused. This question could have more than one answer. READ MORE
