What is the required minimum number of outlets for a dwelling unit?

The correct answer emphasizes the importance of ensuring adequate electrical outlets in a dwelling unit by stating that there must be at least one outlet in wall spaces that are 2 feet or longer. This requirement is established to promote safety and functionality. In residential settings, having sufficient outlets prevents the use of excessive extension cords and minimizes the risk of overloading circuits.

In practical terms, this means that if a wall space is at least 2 feet in length, occupants can expect to find an outlet there, which ensures that the location is suitable for various electrical devices without risking safety hazards. This regulation helps uphold residential wiring standards that contribute to both convenience and adherence to electrical codes.

Other options suggest varying standards that are either too vague or insufficient, such as having just one outlet per room or per floor, which does not address the need for accessibility and safe electrical practices throughout a dwelling. Additionally, the claim that no specific requirement exists is incorrect since national and local electrical codes outline clear guidelines for outlet placement to protect residents and ensure a well-equipped living space.
