According to code, a receptacle is required to be installed in any wall space that is how wide or more?

The requirement for receptacles in residential wiring is based on the width of the wall space that is accessible. According to the National Electrical Code (NEC), receptacles must be installed in wall spaces that are 24 inches wide or more. This is to ensure that there are sufficient opportunities for plug-in access in areas where people might commonly use electrical devices. Each wall space that measures 24 inches in width or more must have at least one receptacle, ensuring that areas of a room, such as living rooms and bedrooms, have practical locations for electrical devices. This rule helps to prevent the use of extension cords, which can pose hazards if not managed properly.
