What is the minimum wall space width that requires receptacle outlets to be installed?

The minimum wall space width that requires receptacle outlets to be installed is 24 inches (600mm). This requirement is based on electrical codes which dictate that wall spaces that are 24 inches wide or more should be equipped with a receptacle outlet to ensure accessibility for electrical devices.

This standard helps reduce the reliance on extension cords and provides convenient access to power in living spaces. The guideline is part of the design practices aimed at enhancing safety and functionality in residential wiring, ensuring that outlets are within reach for different areas of the room, including areas where furniture may be placed.

Other width measurements, such as 12 inches, 18 inches, and 30 inches, do not meet this minimum requirement established by electrical codes. For example, a wall space of 12 inches or 18 inches is considered too narrow to necessitate an outlet, as it typically may not be usable for placing larger furniture or appliances where access to power is necessary. A wall space of 30 inches does exceed the minimum requirement, but it does not specifically address the minimum threshold necessary for outlet installation. Therefore, the correct answer emphasizes the importance of establishing guidelines that provide safe and functional electrical access in residential environments.
