Sample 1 — Wiring Methods and Materials
Question: Devices operating at 240 volts nominal are mounted within a metal cabinet. What is the minimum airspace required between the walls, back, metal gutter partition, or door of the cabinet and the nearest exposed current-carrying part of those devices?
- A. 1 in.
- B. 1/2 in.
- C. 3/4 in.
- D. 1/4 in.
Correct Answer: B
NEC 2014, Section 312.11(A)(3) requires at least 12.7 mm (0.500 in.) of airspace where the voltage does not exceed 250, increased to at least 25.4 mm (1.00 in.) for nominal voltages of 251 to 1000.
Reference: NEC 2014 Section 312.11(A)(3)
Sample 2 — Branch Circuits and Conductors
Question: Arc energy reduction means such as zone-selective interlocking, differential relaying, or energy-reducing maintenance switching are required for a circuit breaker when the highest continuous current trip setting for which the installed overcurrent device is rated or can be adjusted is at least how many amperes?
- A. 1200 amperes
- B. 1600 amperes
- C. 600 amperes
- D. 800 amperes
Correct Answer: A
NEC 240.87 applies where the highest continuous current trip setting for which the actual overcurrent device installed in a circuit breaker is rated or can be adjusted is 1200 A or higher; one of the listed clearing-time reduction methods (or an approved equivalent) must then be provided, along with documentation of the breaker location.
Reference: NEC 2014 Section 240.87
Sample 3 — Equipment and Devices
Question: A low-voltage display lighting system operating at 30 volts or less is being supplied in a retail store. The branch circuit supplying the system's power supply shall be rated at a maximum of:
- A. 25 amperes
- B. 20 amperes
- C. 30 amperes
- D. 15 amperes
Correct Answer: B
Per NEC 2014, Section 411.7, lighting systems covered by Article 411 shall be supplied from a maximum 20-ampere branch circuit.
Reference: NEC 2014 Section 411.7
