Open electrical service conductors and multi-conductor cables should have a clearance of at least _____ feet from the sides of doors, porches, and operable windows.

The requirement for open electrical service conductors and multi-conductor cables to maintain a minimum clearance from the sides of doors, porches, and operable windows is rooted in safety standards. A clearance of at least 3 feet is necessary to reduce the risk of accidental contact with live electrical conductors, which could lead to electrical shock or other hazards. Ensuring this distance provides a buffer that helps to prevent incidents during routine activities such as entering or exiting a building, as well as when using windows.

This standard is in place to promote safe practices in electrical installations and to safeguard individuals against potential electrical hazards that could arise from improper proximity of electrical components to areas of frequent human activity.
