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. Reference: NFPA 70E®: Electrical Safety in the Workplace and Handbook Set, 2009 Edition John |

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. |
