Section 230.9 covers clearance from building openings for service conductors, and final spans are required to comply with 230.9(A), (B) and (C). In 230.9 (A), covering clearance from windows, it states that: “Service conductors installed as open conductors, or multi-conductor cable without an overall outer jacket shall have a clearance of not less than 3 ft from windows that are designed to be opened, doors, porches, balconies, ladders, stairs, fire escapes or similar locations. Exception: Conductors run above the top level of a window shall be permitted to be less than the 3-ft requirement.”
I would also question this installation that may also be in violation of the rule found in 230.70(A) where a “means shall be provided to disconnect all conductors in a building, or other structure from the service-entrance conductors.”
The location of the service disconnecting means is required to be installed in accordance with 230.70(A)(1), (2) and (3). 230.70(1) requires the service disconnecting means to be installed at a “readily accessible” location (see Article 100 definition) either outside of a building or structure or inside “nearest the point of entrance” of the service conductors.
