Nfpa 70e Report on Comments

[brother]

I was reading the ROC on the new NFPA 70E that is comming out in 2012, and I was curious if any one knew why they upgraded the "Panaboards or other equipment rated 240v and below Circuit breaker or fused switch operation with covers on" column to a Hazard/Risk Category of 1 from 0??

I think this one is being a little overboard and may discourage some companies and electricians from complying with NFPA 70E. Whats your opinion?
Haz/risk catagory 1 is including the Arc rated face shield or arc flash suit hood, and having leather gloves. The face shield is a bit much I think for the operation of a single 20 amp breaker on 120v circuit.

It would be helpful when you ask such a question that you include the ROC Comment or Log number. I went through the ROC and found only one Comment (70E-346, Log #366) that seemed to suggest revising the HRC from 0 to 1 for the application. Since it was rejected your question is moot.

Just what is the difference in risk of operating a 20A CB at a panelboard or a lightswitch that is on that same branch circuit 5 feet away. It seems like we are headed to either having to put on a moonsuit to turn on the lights or some expensive and elaborate setup to solve a problem that never actually existed.
