The “Other” 70E Arc Flash Analysis Table

By Robert LeRoy, CESCP

other table 2 webUsers of the NFPA 70 (National Electrical Code) know the organizational system all too well. According to this blog post on www.plantservices.com, if the information is in the first 8 chapters, it generally is applicable. Chapter 9 is a transitional chapter where only what’s referenced in one of the previous 8 chapters may apply. The rest of the information in Chapter 9 and all the annexes isn’t mandatory, and is there for engineers and inspectors to argue some minor point. If it were really important, it would be in the main body of the book, right?

This is not an accurate portrayal of the reason the organizers of this great document placed the information as they did. By following the NFPA format used in the NEC, many people have missed the substantive and useful information in the back of the book.

Read the full blog post from Plant Services magazine to lean more about why every chapter in the NEC® Code is important.
