Which of the following is NOT a required clearance under electrical inspection guidelines?

In electrical inspection guidelines, the required clearances between overhead electrical conductors and various areas ensure safety and accessibility. The correct choice indicates a height clearance that is typically not mandated over residential rooftops.

The requirements usually specify higher clearances for areas where people may be present or where equipment is operated, such as over driveways, walkways, and swimming pools. These areas often have specific height requirements due to the potential risk of contact with power lines, which can pose significant safety hazards.

In contrast, the clearance over residential rooftops tends to be lower because rooftops are not areas where people are frequently present in direct proximity to electrical lines, especially compared to driveways or walkways. Consequently, maintaining a clearance of eight feet over residential rooftops does not meet the same safety concerns as the other specified areas, making it not a requirement under electrical inspection guidelines.
