this is required reading for one of my classes for 1st semester in a local community college. Very thorough and full of super-clear diagrams and photos. Also, full of references to related NEC rules for residential wiring. Highly highly recommended whether you are pursuing an electrical career, or just serious about understanding the wiring in your own house from the from service entrance to 3-way and 4-way switches, and how to do things safely and to code. I bought this used, and it was in great shape,
