Sample 1 — Wiring Methods and Materials
Question: You are a journeyman electrician installing PVC conduit on the exterior of a warehouse. The area is subject to physical damage from forklifts and loading equipment. Which type of PVC conduit is identified for use in areas of physical damage?
- A. Schedule 40 PVC
- B. Type EB PVC
- C. Schedule 20 PVC
- D. Schedule 80 PVC
Correct Answer: D
Per NEC 352.10(F), PVC conduit used exposed in areas of physical damage shall be identified for the use. The Informational Note states that PVC Conduit, Type Schedule 80, is identified for areas of physical damage.
Reference: NEC 2020 Section 352.10(F)
Sample 2 — Services and Service Equipment
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 2020 Section 250.66(B), Table 250.66
Sample 3 — Branch Circuits and Conductors
Question: A single-family dwelling with a 120/240-volt, single-phase service has a calculated load of 154 amps. Using 75°C rated copper THWN-2 conductors, what is the minimum service conductor size?
- A. 1 AWG
- B. 1/0 AWG
- C. 2/0 AWG
- D. 3/0 AWG
Correct Answer: B
Step 1: A 154 A calculated load needs a service rated at least 154 A; the next standard rating is 175 A (240.6(A)).
Step 2: For a one-family dwelling supplied by a 120/240-volt, single-phase service, the NEC permits service conductors with an ampacity of not less than 83% of the service rating (310.12(A)): 175 A × 0.83 = 145.25 A.
Step 3: In the 75°C copper column of Table 310.16, 1 AWG = 130 A (too small) and 1/0 AWG = 150 A, so 1/0 AWG copper is the minimum. Table 310.12(A) likewise lists 1/0 AWG copper for a 175 A dwelling service.
2/0 AWG (175 A) is what you get by sizing for the full 154 A with Table 310.16 alone, without the dwelling allowance.
Reference: NEC 2020 Table 310.12 (310.12(A))
