Service conductors must have a clearance of not less than how many feet from windows, doors, or similar openings?

Service conductors must maintain a clearance of not less than 3 feet from windows, doors, or similar openings to ensure safety and accessibility. This distance is critical for several reasons.

First, it helps to prevent accidental contact with the conductors by individuals accessing or using doors and windows. A greater distance reduces the risk of an accidental electrical shock or injury that could occur if someone were to come too close to live conductors.

Second, this clearance requirement ensures that there is enough space for maintenance and emergency personnel to work safely without the hazard of coming into close proximity with electrical conductors. It allows for the safe operation of windows and doors without the obstruction of electrical wiring.

These guidelines are established by the National Electrical Code (NEC) and are essential for maintaining electrical safety standards in both residential and commercial settings.
