In a dwelling unit, which wall space width necessitates the installation of a receptacle?

In a dwelling unit, the National Electrical Code (NEC) specifies that any wall space that is 2 feet or greater in width must have a receptacle installed. This requirement is intended to ensure that electrical receptacles are conveniently located so that they can accommodate the needs of occupants and prevent the use of extension cords in ways that could lead to a safety hazard.

The specific reason for choosing 2 feet is that this measurement allows for the proper placement of receptacles in areas where furniture could be located, ensuring that outlets are accessible for typical use without excessive reach. This reinforces the principle of providing ample access to electrical power in living spaces to enhance safety and functionality.

Other widths, such as 1 foot, 3 feet, and 4 feet, are not included in this requirement because they either do not meet the minimum wall space width criterion or exceed what is necessary for proper receptacle coverage. By focusing on the 2-foot minimum, the NEC helps ensure a balanced approach to electrical access throughout dwelling units.
