Sample 1 — Services, Feeders, and Branch Circuits
Question: According to NEC Section 215.4(A), up to how many sets of 3-wire feeders are permitted to utilize a common neutral conductor?
- A. Two sets
- B. Three sets
- C. Four sets
- D. Five sets
Correct Answer: B
According to the National Electrical Code or National Electrical Code Handbook (Page 93), Section 215.4(A) states that up to three sets of 3-wire feeders or two sets of 4-wire or 5-wire feeders shall be permitted to utilize a common neutral.
Reference: NEC 2017 Section 215.4(A)
Sample 2 — Grounding and Bonding
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 2017 Section 250.66(B), Table 250.66
Sample 3 — Raceways and Boxes
Question: Which of the following is a permitted use for Liquidtight Flexible Metal Conduit (LFMC)?
- A. Where subject to physical damage
- B. For direct burial where listed and marked for the purpose
- C. In locations where the operating temperature exceeds the material's listed rating
- D. As a substitute for rigid metal conduit in all hazardous locations
Correct Answer: B
Per NEC 350.10(3), LFMC shall be permitted for direct burial where listed and marked for the purpose. Section 350.12 prohibits LFMC where subject to physical damage or where temperature limits are exceeded.
Reference: NEC 2017 Section 350.10(3)
