What is the minimum clearance required for unjacketed multiconductor cable service conductors from windows and doors?

The minimum clearance required for unjacketed multiconductor cable service conductors from windows and doors is indeed 3 feet. This requirement is outlined in the National Electrical Code (NEC) to ensure safety and reduce the risk of accidental contact or damage.

The 3-foot clearance serves several important purposes. First, it helps to prevent the possibility of someone inadvertently coming into contact with the conductors, which could lead to electric shock or other dangerous situations. Additionally, maintaining this distance helps to minimize the likelihood of physical damage to the cable, which could result from opening or closing windows and doors.

This standard is particularly significant in residential and commercial settings where the movement of people and objects around doorways and windows is frequent. The NEC establishes such clearance requirements as part of its broader goal of ensuring electrical safety in installations, thereby protecting both individuals and property.

Other potential clearances suggested might not align with the NEC's focus on preventing hazards associated with electrical installations around accessible areas.
