Sample 1 — Low-voltage Communication and Sound Systems
Question: A fused-type primary protector is installed on a communications circuit. Its terminals are required to be marked to indicate which of the following?
- A. Input, output, and ground
- B. Line and ground
- C. Line, load, and ground
- D. Line, instrument, and ground
Correct Answer: D
NEC 2023, 805.90(A)(2) states that fused-type primary protectors consist of an arrester connected between each line conductor and ground, a fuse in series with each line conductor, and an appropriate mounting arrangement, and that primary protector terminals shall be marked to indicate line, instrument, and ground, as applicable. (A listed primary protector under 805.170(A) is marked line and ground.)
Reference: NEC 2023 Section 805.90(A)(2)
Sample 2 — General Knowledge
Question: Which chapter of the Code covers communications systems and is not subject to the requirements of Chapters 1 through 7 except where those requirements are specifically referenced?
- A. Chapter 9
- B. Chapter 7
- C. Chapter 8
- D. Chapter 5
Correct Answer: C
NEC 2023, 90.3 states that Chapter 8 covers communications systems and is not subject to the requirements of Chapters 1 through 7 except where the requirements are specifically referenced in Chapter 8. Chapters 5, 6, and 7 cover special occupancies, equipment, and conditions; Chapter 9 consists of tables applicable as referenced.
Reference: NEC 2023 Section 90.3
Sample 3 — Low-voltage Remote Control and Alarm Systems
Question: A raceway contains only Class 1 remote-control circuit conductors. The ampacity adjustment factors for more than three current-carrying conductors apply only where those Class 1 conductors carry continuous loads in excess of what percentage of the ampacity of each conductor?
- A. 50 percent
- B. 25 percent
- C. 80 percent
- D. 10 percent
Correct Answer: D
Per NEC 724.51(A), where only Class 1 circuit conductors are in a raceway, the number of conductors is determined by 300.17, and the ampacity adjustment factors of 310.15(C)(1) apply only if such conductors carry continuous loads in excess of 10 percent of the ampacity of each conductor. The 80 percent figure relates to continuous-load sizing elsewhere in the Code and is a common misapplication here.

Your first score is just a starting point. After every attempt, the results page shows how you did on each outline topic, so you can see what to work on next. Compare your score with the real exam's passing score, a minimum score of 75, and keep at it until you pass consistently.
- Start with the questions you know. Go through the whole exam once and bookmark anything you're unsure about. Our practice exams let you bookmark and come back.
- Circle back to your bookmarks on the second pass.
- Keep an eye on your pace. The real exam works out to about 3 minutes 36 seconds per question.
- Turn every miss into a lesson. After each attempt, look up each missed question's reference in your book and read the section.
