Ok, I'll get this one going. I for one find this pretty fascinating, but it raises more questions than answers in my mind.
First I commend the state of New Hampshire for compiling this data. I wonder how many other states do it. It seems like NH takes inspections seriously.
New Hampshire, like most New England states, has strict apprenticeship, licensing, inspections, and continuing education. So I am a bit surprised to see the list that was presented. Therefore, one can draw a few conclusions from the data:
1) Even with the best system in place (apprenticeship, licensing, and inspections), many electricians are still making basic mistakes.
2) Perhaps the NEC is not as user-friendly as many of us (particluarly on these NEC related chat forums) might think, and that the average electrician has a hard time using and/or understanding it.
3) Perhaps New Hampshire is not doing a good enough job teaching its apprentices and keeping its license holders updated on the code changes.
4) Perhaps New Hampshire is doing a good job teaching and updating its electrical trade but the trade is simply ignoring the rules. After all, NH is a New England state full of Yankees that don't take correction or change very well.
I can certainly say that about myself as I am a native New Englander.
5) Perhaps the contractors installing emergency systems, fire pumps, and generators need to take a crash course on the NEC and brush up on the fundamentals.
