The correct minimum distance for conductors from doors, porches, and similar locations is indeed 3 feet. This requirement is set to ensure safety and accessibility around areas where people frequently move in and out. Maintaining this distance helps prevent accidental contact with electrical conductors, reducing the risk of electrocution or electrical hazards, especially where outdoor activities or access points are involved.

This 3-foot requirement is particularly important in residential settings, where the risk of someone brushing against or being inadvertently exposed to electrical conductors is higher due to frequent foot traffic. Additionally, adhering to this distance can help in maintaining compliance with local electrical codes, which are designed to protect both the electrical system and the safety of individuals who use the space.

It's worth noting that the other distances mentioned do not align with the established safety guidelines specific to the proximity of conductors in these areas, which focus on minimizing risk while promoting safe usage around electrical installations.
