On the NFPA web site, the new 2009 NFPA standard seems to be released.
Did anyone saw the new Annex D and the calculations. Are there significant modifications between the old standard.

Since the 2004 70E annex calculations were mostly from IEEE 1584 and the older NFPA formulas and neither of those methods havechanged, I would imagine new 2009 70E kept the same ones.
