Arc Flash Boundaries in Small Facilities

I noticed an article published on Reliability that addresses arc flash safety in small facilities. This is a topic that is not commonly covered. The article by John C. Klingler, P.E. of Lewellyn Technology states:

"In small facilities such as small businesses and offices that only use 240 volts and less and have minor power requirements (primarily lighting and receptacle loads), it may not be practical or economical to calculate arc-flash boundaries. It appears the authors of 70E realized this, so they established a default flash boundary that can be used without calculations."

If you work in a small facility, you may find this article about Understanding NFPA 70E to be useful.
