Service conductors installed as unjacketed multi-conductor cable must maintain what minimum clearance from windows that are designed to be opened?

1. 2 feet

2. 3 feet

3. 4 feet

4. 5 feet

The correct answer is: 3 feet

The minimum clearance requirement for unjacketed multi-conductor cable from windows that can be opened is established to ensure safety and prevent potential hazards. Specifically, a clearance of 3 feet is mandated to ensure that the conductors are kept at a safe distance from the areas where people are likely to interact with the window. This clearance helps minimize risks associated with accidental contact with the conductors, which could occur if the window is opened. Additionally, it serves to protect the conductors from potential damage or exposure to environmental elements when the window is in use. In electrical installations, adhering to clearance guidelines is critical for maintaining safety standards, promoting safe accessibility, and preventing electrical hazards. The other specified clearances would not sufficiently address these safety concerns, making 3 feet the appropriate distance to maintain for both protection of the electrical conductors and the individuals using the windows.
