| Exactly! There is always some info troll that will debate the stated rules | for a loophole somewhere. That is why the code is stated with so many words. | people that cannot read shouldn't be wiring homes or businesses where people | can die in fire because of bad techniques or ignorance.
But there is wording in the NEC that if taken literally is wrong. That wording depends on one having experience as an electrician, or having at least done a lot of wiring and/or studied electricity. The problem is that people really do read the NEC (because it is the "final authority") and as a result can come away with the wrong idea. That would be the reader's fault if the wording was literally correct. But it states "rating" instead of "configuration". In this case it is the writers that have it wrong. It's not wrong to those with experience because they can draw on that experience and know what is meant. But some people who don't have that experience will be using the NEC because they have to.

But it is something that DIY-ers are doing a lot more of, and the NEC needs to be able to guide them precisely. If that comes in the form of a separate document just for DIY usage, that might be better. But one of the existing "home wiring done easy" type books is not it because it is not, by itself in any way, authoritative. What I am referring to is a separate book that can entirely stand on its own such that being in compliance with that book is being in compliance, and the primary NEC document will never need to be consulted. It would not allow anything the NEC would not allow, but might not allow some things the NEC does.
One problem NEC does face is having to handle both extremes from DIY home wiring to industrial electricians doing major work site wiring. It's not easy. But be separating things, I think it could be made to work by relaxing the need to handle any commercial situations in the new document. I'll even suggest the name "NEC @ Home" to give it the cool modern sounding name. And again, it is not a how-to do wiring book ... it is a rule book. It supplements a wiring book (and may be licensed by NFPA, if they ever develop this, to be included in such books if they wish).
