Receptacle outlets must be installed in any wall space that is how wide or more?

For residential wiring, the National Electrical Code (NEC) specifies that receptacle outlets must be installed in wall spaces that are wider than a certain width to ensure accessibility for electrical devices. A wall space is defined as any section of wall that is more than 2 feet (24 inches) wide. This regulation signifies that areas with this width or greater must be equipped with at least one receptacle outlet to accommodate the needs of occupants.

By setting the requirement at 24 inches, the code addresses practical concerns that arise in typical residential living spaces. This ensures that individuals have sufficient access to electrical power where it is most likely needed, thus promoting safety and convenience within living areas.

The other options do not align with the NEC standards that apply to receptacle spacing and placements. Therefore, the requirement for receptacle outlets in wall spaces that are 24 inches or wider is a crucial principle in residential wiring, aimed at enhancing functionality and safety within the home.
