The point of attachment of overhead service conductors to a building must be at least what height above finished grade?
a.10 ft
b.12 ft
c.8 ft
d.15 ft
Explanation
Per 230.26, the point of attachment must not be less than 10 ft (3.0 m) above finished grade and must be located so the minimum service-drop clearances of 230.24 are still met. Lower values do not satisfy the code minimum, and 12 ft/15 ft exceed the required attachment height.
