Sample 1 — Wiring Methods and Terminations
Question: What is the ampacity rating basis for Type UF cable?
- A. 75°C (167°F) conductors
- B. 90°C (194°F) conductors
- C. 60°C (140°F) conductors
- D. 105°C (221°F) conductors
Correct Answer: C
Per NEC 340.80, the ampacity of Type UF cable shall be that of 60°C (140°F) conductors in accordance with 310.14.
Reference: NEC 2020 Section 340.80
Sample 2 — 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)
Sample 3 — Laws, Rules, Basic Business Practices, and Practical Applications
Question: You are the only member of your newly formed electrical contracting limited liability company and make no special tax election. For tax purposes, how is that LLC treated?
