Sample 1 — Wiring Methods & Materials
Question: When bare or covered conductors are installed together with insulated conductors, how is the temperature rating of the bare or covered conductor determined for ampacity purposes?
- A. It is rated at the highest temperature rating among all conductors in the raceway
- B. It is rated at 60°C regardless of the insulated conductors present
- C. It is set equal to the lowest temperature rating of the insulated conductors
- D. It is rated at 75°C unless the equipment termination requires otherwise
Correct Answer: C
Per NEC 310.15(D), where bare or covered conductors are installed with insulated conductors, the temperature rating of the bare or covered conductor shall be equal to the lowest temperature rating of the insulated conductors for the purpose of determining ampacity.
Reference: NEC 2023 Section 310.15(D)
Sample 2 — Wiring & Protection
Question: A 400 A service uses 600 kcmil copper service conductors. What is the minimum size of a copper grounding electrode conductor that runs only to a concrete-encased electrode?
- A. 2 AWG
- B. 4 AWG
- C. 3/0 AWG
- D. 1/0 AWG
Correct Answer: B
Table 250.66 would require a 1/0 AWG copper grounding electrode conductor for 600 kcmil copper service conductors, but 250.66(B) says a grounding electrode conductor (or bonding jumper) that runs only to a concrete-encased electrode is not required to be larger than 4 AWG copper. So the minimum size required here is 4 AWG copper.
Reference: NEC 2023 Section 250.66(B), Table 250.66
Sample 3 — General Electrical Knowledge
Question: A dc motor on a 220-volt circuit draws 40 amperes through a two-wire feeder. Each of the two feeder conductors has a resistance of 0.3 ohm. What is the total power lost as heat in the feeder conductors?
- A. 960 W
- B. 480 W
- C. 1,920 W
- D. 8,800 W
Correct Answer: A
Per the American Electricians' Handbook (Secs. 111 and 158), conductor heat loss is W = I²R, where R is the resistance of BOTH conductors: 0.3 + 0.3 = 0.6 ohm. W = 40² × 0.6 = 1600 × 0.6 = 960 W. Using only one conductor gives 480 W; 8,800 W is the total motor input (E × I), not the line loss.
