What is the required clearance of open electrical service conductors not installed in a raceway from the sides of doors or windows?

The required clearance of open electrical service conductors not installed in a raceway from the sides of doors or windows is indeed three feet. This regulation is in place to ensure safety and prevent potential hazards. Maintaining this clearance minimizes the risk of accidental contact with the conductors when doors or windows are opened or closed, which could lead to electrical shock or short circuits if the conductors are damaged.

This three-foot clearance is a critical component of electrical safety standards, helping to ensure that electrical installations are protected from everyday activities in a home. By adhering to this requirement, inspectors and electricians can better ensure that the electrical service is both functional and safe for occupants.
