  2. The NEC is broken up into 9 Major CHAPTERS:(Try to Identify each chapter.) 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - Def (100) & Gen Requirements (110) Wiring & Protection(200-285) Wiring Methods & Materials (300-398) Equipment for General USE (400-490) Special Occupancies (500-590) Special Equipment (600-695) Special Conditions (700-780) Communications (800-830) Tables 1,2,4,5,8, Annexes, Index

  3. Def (100) & Gen Requirements (110) Wiring & Protection (200-285) Wiring Methods & Materials (m&m’s) (300-398) Stuff we USE every day (400-490) Scary (Hazardous) Places (500-590) WeirdIndustry (600-695) 911 Emergency (700-780) Communications – TV, Radio, Antennas, Network (800-830) Tables 1(53,31,40),2 (Bends),4(Conduit Area),5 (Conductor Area),8(Ohms) 1- 2- 3- 4- 5- 6- 7- 8- 9- The NEC 9 Major CHAPTERS:(as each chapter is displayed, here’s a little different way of seeing them to help you remember.)

  4. Now that you know basically what’s in each of the CHAPTERS: It’s time to go through the ARTICLES in each Chapter.

  5. Don’t forget about ARTICLE 90 which basically says: • DON’T ARGUE WITH YOUR INSPECTOR! He/She is the one who will pass or fail your job. Remember, AHJ Rules!

  6. Chapter 1 • 100 • 110 Definitions – These are the basic ones. Each chapter has more definitions. Keep this in mind. They will be in PART I(if there are PARTS) of every ARTICLE, if applicable! How tall, how far, how tight, how Safe, how labeled, how guarded, tunnels and manholes

  7. Chapter 2Wiring & Protection There are 20 questions on test from this chapter.

  34. About the Examination: • KNOWCHAPTERS 2, 3 & 4.52 out of 80QUESTIONS (65%) of the test focus on these chapters! Know these! • SKIP ALL CALCULATIONS UNTIL THE END. THEY’LL take TOO MUCH PRECIOUS TIME! • READ THE QUESTION SLOWLY & CAREFULLY! They will try to trick you. • RELAX. Use the first minute or two to close your eyes and visualize each article number and basic content. This will help organize your thoughts, calm test anxiety and reassure you that you know the code book. If you’ve done your flash cards & this presentation thoroughly, you’ll be prepared.
