Sample 1 — Laws, Rules, Basic Business Practices, and Practical Applications
Question: As the service provider for a commercial fire alarm system, you take the system out of service to replace a failed control unit, and the replacement will not arrive for two days. In addition to notifying the system owner of the impairment, you must report the condition to the authority having jurisdiction when the system has been out of service for more than ______.
- A. 8 hours
- B. 24 hours
- C. 72 hours
- D. 48 hours
Correct Answer: A
NFPA 72, 10.21.4 requires the service provider to report to the authority having jurisdiction any fire alarm system that is out of service more than 8 hours. The owner notification requirement is in 10.21.1, and the impairment record must be retained 1 year per 10.21.2.
Reference: National Fire Alarm Code (NFPA 72), 10.21.4
Sample 2 — Wiring Methods and Terminations
Question: You are running Type MC cable along an exposed wall in a commercial building. What is the maximum interval at which the cable must be secured?
- A. 1.2 m (4 ft)
- B. 1.4 m (4½ ft)
- C. 1.8 m (6 ft)
- D. 2.4 m (8 ft)
Correct Answer: C
Per NEC 330.30(B), unless otherwise provided, Type MC cables shall be secured at intervals not exceeding 1.8 m (6 ft).
Reference: NEC 2020 Section 330.30(B)
Sample 3 — General
Question: What is the definition of 'ampacity' as it applies to electrical conductors?
- A. The maximum voltage a conductor can withstand without insulation breakdown
- B. The maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating
- C. The total resistance of a conductor measured in ohms per thousand feet
- D. The minimum current required to trip the overcurrent protection device for that conductor
Correct Answer: B
Per NEC Article 100, 'Ampacity' is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. This is a fundamental definition used throughout the Code for conductor sizing.
Reference: NEC 2020 Article 100 (Definitions)
