Re: NEC pocket guides
Pocket Guides......you had to get me started.
They are good for only one purpose: a quick reference for a person that has spent some time with their nose in the code book.
All too often I get into it with an electrician that believes that what is in the little card, pamphlet, what have you is all there is. I can't tell you how many times I have seen motors, welders, etc. conductors sized to the over current device. When I point out to them about the modification to the first part code in the remaining 3/4 of the NEC that allows them to use smaller wire, they look at me like I'm some sort of penny pinching miser that wants to burn down the installation.
Same thing with the bolt-in panels that also permits(for lack of a better word) the installation of the snap in version of circuit breakers. Not mentioning a brand here because I don't want to give anyone any ideas. grrrrr
