Apprentices, journeyman, contractors, engineers, designers, and estimators alike will benefit from this positive, systematic approach to understanding the Code®. Readers are encouraged to first examine a section from the Code® Book before referring to the correlating annotations in this manual. Where questions are used to illustrate the “applied codeology” system, users are requested to locate the answer in the suggested Code® article before checking the answer in this book. This methodical handling of and practice using the Code® Book encourages proficiency in users, and soon they will be able to decide where the answer is located before the Code® Book is even opened. The result is better electrical installations through a higher Code understanding, as well as optimization of the Code® Book as a first-rate tool of the trade.
