Sample 1 — Wiring Methods and Terminations
Question: You are installing a conduit run on a rooftop for a commercial HVAC system. The conduit is mounted directly on the roof surface with less than 23 mm (7/8 in.) clearance above the roof. The outdoor temperature is 40°C (104°F). What ambient temperature must you use to apply correction factors from the ampacity tables?
- A. 40°C (104°F)
- B. 53°C (127°F)
- C. 63°C (145°F)
- D. 73°C (164°F)
Correct Answer: D
Per NEC 310.15(B)(2), for raceways or cables exposed to direct sunlight on or above rooftops where the distance above the roof is less than 23 mm (7/8 in.), a temperature adder of 33°C (60°F) shall be added to the outdoor temperature. 40°C + 33°C = 73°C (104°F + 60°F = 164°F).
Reference: NEC 2020 Section 310.15(B)(2)
Sample 2 — Laws, Rules, Basic Business Practices, and Practical Applications
