Working on some arc flash labels, and going through the latest edition of NFPA 70E (2015). I have a few questions:
1. Is PPE required to turn a circuit breaker on or off with the covers in place?
Table 130.7(C)(15)(A)(a) seems to say PPE would not be required. But 130.5(C) seems to indicate if an incident energy analysis is performed, then you can't also use the PPE category method. That would mean I can't use the table 130.7(C)(15)(A)(a).
2. 130.5(C) states either the incident energy method or PPE Categories Method can be used to determine the arc flash PPE, but not both. Why not both? It doesn't make any sense to me.
3. 130.5 (C) also states
Again, why not? That table should provide PPE for the incident energy levels, so why can't it be used? Shouldn't using this table result in PPE that is equivalent to the PPE selected from table H.3(b)??
4. Is the hazard category "Dangerous" gone? My version of SKM lists a Dangerous category for any energy levels over 40 cal/cm2. It basically made the label state "No PPE found" and "Do not work on Hot." This relates back to my first question. If PPE is required to operate a breaker, and if there wasn't any PPE available for the energy level, how could anyone ever turn the breaker on or off? Is that issue gone now?
5. Is the latest version of NFPA 70E automatically required to meet OSHA compliance?

Code:
"The results of an incident energy analysis to specify an arc flash PPE Category in table 130.7(C)(16) shall not be permitted."
