It is a pity that the NEC is so expensive ($85 list $67 Amazon) and changes with revisions every three years. It is a book that should be on a lot of amateur's bookshelves. Not always easy reading but is very carefully written and defines best practices. Interestingly enough it is published by the National Fire Protection Association (NFPA). Insurance companies are not interested in paying out so they want things to be done safely. This is a good example of industry and government cooperation. The industry experts figure out what is best and safest. The government makes people pay attention. My son and I had a lot of fun taking NEC rules and discussing not the rule but the reason the rule was there. Guess we were a couple of nerds. But the rules were not arbitrary. There was always a safety related reason.
