Sample 1 — Wiring Methods, Materials, and Conductors
Question: NM cables containing two or more current-carrying conductors are bundled without spacing through a single opening in wood framing that will be sealed with caulk or foam. Ampacity adjustment factors must be applied when the number of such cables through that opening exceeds how many?
- A. One
- B. Three
- C. Four
- D. Two
Correct Answer: D
Per NEC 2014, 334.80, where more than two NM cables containing two or more current-carrying conductors pass through the same opening in wood framing that is to be sealed with thermal insulation, caulk, or sealing foam, the allowable ampacity of each conductor must be adjusted in accordance with Table 310.15(B)(3)(a).
Reference: NEC 2014 Section 334.80
Sample 2 — Utilization Equipment and Devices
Question: A luminaire shall NOT be supported by the screw shell of a lampholder when it exceeds which of the following limits?
- A. 10 lb or 20 in. in any dimension
- B. 15 lb or 24 in. in any dimension
- C. 3 lb or 12 in. in any dimension
- D. 6 lb or 16 in. in any dimension
Correct Answer: D
Per NEC 2014, 410.30(A), luminaires and lampholders shall be securely supported, and a luminaire that weighs more than 3 kg (6 lb) or exceeds 400 mm (16 in.) in any dimension shall not be supported by the screw shell of a lampholder.
Reference: NEC 2014 Section 410.30(A)
Sample 3 — Grounding and Overcurrent Protection
Question: You are rewiring a long feeder run in a plant and the ungrounded conductors are being installed larger than the minimum size needed for ampacity in order to limit voltage drop. How must the wire-type equipment grounding conductor installed with them be treated?
- A. Sized solely from the overcurrent device rating
- B. Increased by one AWG trade size
- C. Sized to match the ungrounded conductors
- D. Increased proportionally to circular mil area
Correct Answer: D
NEC 2014, 250.122(B) requires that where ungrounded conductors are increased in size from the minimum size having sufficient ampacity, wire-type equipment grounding conductors shall be increased in size proportionately according to the circular mil area of the ungrounded conductors.
Reference: NEC 2014 Section 250.122(B)
