Keys to Understanding NFPA Standard 70E

A detailed article about NFPA 70E is provided in EC&M Magazine (May 2005 issue).

It provides an overview of the OSHA regulations and a detailed explanations of terms such as "incident energy" and "fault current". The article is written with the objective of bringing a greater technical understanding of NFPA 70E so as to improve safety, and it accomplishes that goal.

The conclusion of the article makes an excellent recommendation:

"Most contractors acknowledge that the calculations required by 70E are too complex for the everyday work environment. That's why it's recommended that the tables in Section 130 be distributed to each and every field worker and that each worker be outfitted with a minimum Category 2 PPE. Electricians' tools should also be reviewed to make sure they comply with 70E. Just simply knowing 70E guidelines will help reduce the number of arc-flash injuries."
