I need opinions from those familiar with the NFPA 70E requirements in the US. I have been told that this part of the code is not really enforceable, it is just mentioned as a footnote to the regular NFPA 70 National lectric Code. Is that true? If so, why bother? Seems to me to be a lot of work to go through all the training and design requirements, only to find out nobody really cares.
