What is the minimum clearance required for unjacketed multiconductor cable installed as service conductors near windows, doors, and similar locations?

The minimum clearance required for unjacketed multiconductor cable installed as service conductors near windows, doors, and similar locations is 3 feet (36 inches). This requirement is in place to ensure safety and accessibility, minimizing the risk of damage to the electrical conductors as well as reducing the likelihood of accidental contact by individuals entering or exiting these spaces.

Service conductors must have adequate clearance to prevent exposure to weather elements and reduce the risk of electrical hazards, especially where people frequently walk or where objects might be placed against the walls. The 3-foot requirement allows for a safe buffer zone around the cable, ensuring that it remains protected while also conforming to safety codes and standards set forth by electrical regulations.

While other potential clearance distances such as 2 feet, 4 feet, or 5 feet may seem reasonable, they either do not meet the specific regulatory requirements or exceed necessary safety measures, making 3 feet the most appropriate choice.
