This 24-hour course starts with a general overview of the larger changes to the NEC. These include code-wide changes, several new articles, and changes to Article 90 for clarity’s sake.
Next, we’ll begin to look at Chapters 1-9 individually. Chapter 1 contains some of the fundamental definitions that electricians should master to be able to apply the rest of the code. Chapter 2 examines the best wiring and protection practices, essential for designing a safe and useful electrical system. Chapter 3 picks up from there, and discusses how to take that design and build the electrical system to be both safe, and effective for its intended use. Chapter 4 addresses the correct way to connect and use these electrical systems when the design and build are applied.
With Chapter 5, we’ll get a bit more specialized. Chapter 5 is entitled “Special Occupations”, and will look at some less common systems you may encounter, It is widely considered the most complex chapter in the NEC, and it is updated frequently.
Chapter 6 continues to look at specialized equipment, such as elevators. The equipment that falls under this category will usually require the manufacturer’s instructions to install properly. This chapter is short, but contains a large number of changes.
Next, Chapter 7 addresses “special” systems that must operate under duress or inhospitable conditions for regular systems. Fire alarm systems, direct-current microgrids, and more are covered here.
Last, we’ll cover Chapters 8 and 9, as well as the informative Annexes to the NEC. Chapter 8 focuses on communication systems, such as telephones and televisions. Chapter 8 is important to study specifically, because it is the only chapter in the NEC which does not necessarily conform to the fundamental rules. Chapter 9 contains tables providing guidance on various aspects of conduits and tubing, as well as how to apply them properly. The informative annexes we’ll look at contain important examples, which will help you apply the code to your work.
The course will conclude with an exam, as required by Wisconsin.
