The spacing of receptacles in living areas ensures that no point along the available floor line perimeter shall exceed how many inches from a receptacle outlet?

In residential construction, the National Electrical Code (NEC) specifies that receptacles must be installed in a manner that ensures all points along the accessible floor line perimeter do not exceed a certain distance from a receptacle outlet. This requirement is designed to enhance the convenience and functionality of electrical access in living areas.

The correct answer is 6 feet because the code stipulates that no point along the floor line perimeter should be more than 6 feet from a receptacle. This distance ensures that individuals have easy access to electrical outlets for the use of various devices, promoting safety by reducing the need for long extension cords and minimizing the risk of tripping hazards.

In contrast, the other distances listed—4 feet, 8 feet, and 10 feet—do not comply with the NEC standards applicable to household living spaces. Setting the maximum distance at 4 feet would likely be excessive, whereas 8 feet and 10 feet would allow too great a spacing between receptacles, leading to potential convenience issues and increased reliance on extension cords, which can create hazards.
