This is a great reference for the beginner who is undertaking a "simple" project. The book is kind of like "Cliffsnotes" for the NEC, and would be very handy for the beginner who does not know that much about electrical installations. It provides easily understood diagrams and descriptions for your everyday home projects, with references to the applicable NEC codes should the user decide to investigate a particular application in more detail. The more advanced users may want a reference with more detail, but this version is great for its intended audience (beginners).
