Just sat through about 8 hours of NFPA 70E training today. It was difficult but I try to keep an open mind. I come from the old school (well, thats relative I guess) where people just know that you don't stick your finger/hand/etc where it doesn't belong when it comes to electrical stuff. Common sense smarts and all. Personally I feel that 70E is a bit overdone and possibly to the point that it coddles stupidity. Before anyone asks I will say yes, I am a fan of natural selection. I am well aware that there are considerable differences between single phase and 3 phase when it comes to incident energy. Also when dealing with 208 or 240 phase-phase as opposed to 480 phase-phase. What really did it for me was the requirement for PPE to reset (or even operate, for that matter) a breaker in a panel at 240 volts or less. Before I take a tongue lashing, I understand that that same simple breaker operation in a 480 panel with 20kA of fault current available is entirely different and should be treated as such. And the NFPA 70E 2015 will be even more stringent. Grrrr.....
