In terms of electrical standards, how high should SE cables be above a roof without significant slope?

  1. 6 feet

  2. 8 feet

  3. 10 feet

  4. 12 feet

The correct answer is: 8 feet

The appropriate height for service entrance (SE) cables above a roof without significant slope is established to ensure safety and accessibility for maintenance and inspections, as well as to minimize the risk of damage or interference with roof activities. When the roof has little to no slope, the National Electrical Code (NEC) specifies that SE cables must be installed at least 8 feet above the highest point of the roof surface. This height provides a sufficient clearance to prevent accidental contact with the cables and allows for safe operational procedures, such as climbing on the roof for repairs or maintenance. In contrast, other height requirements may apply under different conditions or for different types of installations, but in this specific case concerning a roof without significant slope, the standard height is clearly set at 8 feet, making it the correct choice.
