Elzappr had a very good idea about the community college. I teach a NEC class at the local technical colege and had an engineer in my class last semester. He is a foreman at a pharmaceutical factory and wanted to make sure his electricians were wiring according to code. We use Interpreting the National Electric Code by Truman C. Surbrook & Johnathan R. Althouse which can be found on Amazon.com along with an answer book. It covers the entire NEC. I would also recommend any of the Tom Henry books.
