What is the minimum clearance for overhead service conductors above a roof with slope 2 in 12?

• A. 6 ft
• B. 10 ft
• C. 12 ft
• D. 8 ft

Answer: (D)

Maintaining a safe vertical clearance between overhead service conductors and a roof is about preventing contact and giving space for maintenance and weather-related factors. The code sets a fixed minimum clearance above the finished roof surface for residential service conductors, which is eight feet, and this required distance does not change with roof slope. So even with a roof sloped at 2 in 12, you still need at least eight feet of clearance measured from the roof surface upward where the conductors pass. The other options either fall short of this minimum (six feet) or exceed it (ten or twelve feet)—the latter are permissive but not the required minimum for this scenario.
