ABSTRACT
Every chapter in this book will focus on the National Electric Code. The NEC is so important that it also deserves its own chapter at the beginning. Since it is an open-book exam, it is time to start getting close with your friend, the NEC. (Having a positive attitude about your NEC Codebook will help.)
The NEC, which is published by the National Fire Protection Association (NFPA), is published every three years. For instance, you may be taking the exam that is based on the 2014, 2017 or 2020 NEC. Usually NABCEP will adopt the code one to one and a half years after the code is published.
