Open service conductors or multi-conductor cable without an overall jacket shall have a clearance of not less than how many feet from windows, doors, or similar locations that open?

Open service conductors or multi-conductor cable without an overall jacket shall have a clearance of not less than how many feet from windows, doors, or similar locations that open?

• A. 5 feet
• B. 6 feet
• C. 2 feet
• D. 3 feet

Answer: (D)

Open service conductors or multi-conductor cables without an overall jacket are exposed, so a safe distance from openings is required to prevent someone from reaching or contacting energized parts. The minimum clearance from windows, doors, or similar openings that can be opened is three feet. This distance balances safety with practicality, ensuring the conductors aren’t easily touched when openings are used. Distances like two feet are too close, while five or six feet are more conservative than the code requires for this situation.
