safetygem, you are right about 70E 2004 I used the wrong word "adopted" it should have been "recognized". Federal OSHA recognizes NFPA 70E 2004. The last adoption of NFPA 70 was [29 CFR 1926.402(a)] 1984.

[29 CFR 1926.403(i)(2)] Guarding of live parts is where 50 volts or more comes in.

[29 CFR 1926.416(a)]Protection of employees
is where live work will require PPE.

They will use NFPA 70E 2004 to back up their citations as a recognized industry standard. Hopefully they will adopt it.

Thanks for pointing out the use of the wrong word. I'll have to proof read better.
