Sample 1 — Wiring and Protection
Question: You are a journeyman electrician installing service-entrance cables on the exterior of a building. At what maximum interval must the cables be supported by straps or other approved means?
- A. 450 mm (18 in.)
- B. 600 mm (24 in.)
- C. 750 mm (30 in.)
- D. 300 mm (12 in.)
Correct Answer: C
Per NEC 230.51(A), service-entrance cables shall be supported by straps or other approved means within 300 mm (12 in.) of every service head, gooseneck, or connection to a raceway or enclosure and at intervals not exceeding 750 mm (30 in.).
Reference: NEC 2023 Section 230.51(A)
Sample 2 — Selects and Installs Cabinets, Boxes, Fittings, Conduit
Question: What is the minimum conductor size for Type MV cable rated 8001–15,000 volts?
- A. 8 AWG
- B. 6 AWG
- C. 2 AWG
- D. 1 AWG
Correct Answer: C
Per NEC Table 315.12(A), the minimum conductor size for conductors rated 8001–15,000 volts is 2 AWG for copper, aluminum, or copper-clad aluminum. The table lists minimum sizes as: 2001-5000V = 8 AWG, 5001-8000V = 6 AWG, 8001-15,000V = 2 AWG, 15,001-28,000V = 1 AWG, and 28,001-35,000V = 1/0 AWG.
Reference: NEC 2023 Table 315.12(A)
Sample 3 — General Code Requirements
Question: A worker stands in the working space between two 480-volt switchboards that face each other, and both have exposed live parts. What is the minimum depth of working space required?
- A. 3 ft
- B. 4 ft
- C. 5 ft
- D. 6 ft
Correct Answer: B
Exposed live parts on both sides of the working space = Condition 3. Table 110.26(A)(1), 151-600 volts nominal to ground, Condition 3 = 4 ft (1.2 m).
Reference: NEC 2023 Table 110.26(A)(1)
