2011 Version of NFPA-780:

A Quick Overview of Changes from Earlier Versions

Some highlights are summarized below:

Chapter 4, "Protection for Ordinary Structures," is clarified and has new details on air terminals, bonding, stand-off calculations, grounding, and surge protection.

Chapter 8, "Explosives Storage," is 100% re-written. Note to military readers: These details exceed many military codes. Protection methods specified in this chapter may be applied elsewhere by "authorities having jurisdiction" (AHJs).

Annex A, "Explanatory Material," is a must-read section. See page 38, Figure A.4.7.4.1, for an illustration of the Rolling Sphere Method.

Annex L, "Risk Management," is a total re-write.

Annex M, "Personal Safety," contains much new information. This is the ONLY section where personal safety is discussed/ don’t look for any such information in Chapter 4 or elsewhere.

Thanks to the 780 Technical Committee under John Tobias’ leadership for an excellent result in this new version of the standard.
 
Bryan,

Thanks for the input on the 2011 NEC!

Do you; or anyone else on this forum, have any information as to when ICC will start

using the 2011 NEC in their certification tests, and quit using the 2008?

The NFPA 780 is "Installation of Lightning Protection Systems", not the 70, NEC.
