What is the minimum clearance required for overhead open conductors near windows?

The minimum clearance required for overhead open conductors near windows is 3 feet. This standard is set to ensure safety and reduce the risk of electrical hazards. The clearance is important to prevent accidental contact by individuals who may be at windows, especially in areas where activities like cleaning or maintenance might occur. Maintaining this distance helps mitigate the risks associated with electrical shock and supports the safe operation of the electrical system. The requirement is guided by the National Electrical Code (NEC) and is aimed at protecting both the occupants of a building and the integrity of the electrical conductors.
