Sample 1 — Wiring Methods and Materials
Question: A 480V switchboard has exposed live parts front and rear. What is minimum working clearance required?
- A. 3 ft
- B. 4 ft
- C. 5 ft
- D. 6 ft
Correct Answer: B
Exposed live parts on both sides = Condition 3; Table 110.26(A)(1), 151–600V → 4 ft.
Reference: NEC 2023 Table 110.26(A)(1)
Sample 2 — Services and Service Equipment
Question: You are an unlimited electrical contractor installing a Type 1 surge-protective device (SPD) at the service entrance of a new commercial building. To which of the following is the SPD permitted to be connected?
- A. Metal water pipe inside building
- B. Isolated ground bus downstream
- C. Load-side panelboard neutral bar
- D. Grounding electrode conductor
Correct Answer: D
Per NEC 242.13(B), a Type 1 SPD installed at the service must connect to the grounded service conductor, grounding electrode conductor, grounding electrode, or equipment grounding terminal in the service equipment. The grounding electrode conductor is one of the specifically listed permitted connection points. A load-side panelboard neutral bar, an isolated ground bus downstream, or an interior metal water pipe are not among the permitted connection points for a Type 1 SPD at the service.
Reference: NEC 2023 Section 242.13(B)
Sample 3 — Branch Circuits and Conductors
Question: What is the minimum copper service-entrance conductor size for a 200 A, 120/240-volt, single-phase service to a one-family dwelling, using THHN conductors with 75°C terminals?
- A. 2/0 AWG
- B. 3/0 AWG
- C. 250 kcmil
- D. 300 kcmil
Correct Answer: A
For a 120/240-volt, single-phase service supplying the entire load of a one-family dwelling, 310.12(A) (310.15(B)(7) in NEC 2017) permits service conductors with an ampacity of not less than 83 percent of the service rating: 200 A x 0.83 = 166 A. In the 75°C column of Table 310.16, 2/0 AWG copper is rated 175 A, so 2/0 AWG is the minimum. Without that dwelling allowance, 3/0 AWG copper (rated 200 A) would be required.
Reference: NEC 2023 Section 310.12(A), Table 310.16
Treat your first attempt as a checkup, not a verdict. After every attempt, the results page breaks your score down by outline topic, so you can see which topics need work. Compare your score with the real exam's passing score, a minimum score of 70, and keep practicing until you pass consistently.
- Answer what you know first. Go through every question once, answer the ones you know, and bookmark the rest. Our practice exams let you bookmark and come back.
- Come back to your bookmarks. Work them out on your second pass.
- Watch your pace. The real exam works out to about 3 minutes per question.
- Look up every miss. After each attempt, find each missed question's reference in your book and read the section.
