At least one receptacle outlet in bathrooms must be within how many feet of each lavatory basin?

In residential electrical installations, the National Electrical Code (NEC) specifies that at least one receptacle outlet in each bathroom needs to be placed within 3 feet of the lavatory basin. This requirement is in place to ensure that a convenient power source is readily available for devices such as hairdryers, electric shavers, and other personal grooming appliances.

The intention behind this rule is to enhance safety and accessibility in areas where water is present, minimizing the risk of accidents that could occur if individuals need to stretch cords across wet surfaces or locate outlets at a distance. Additionally, ensuring the receptacle is within this proximity promotes the efficient use of electrical devices right where they are needed, contributing to a safer and more practical bathroom environment.

The other options suggest distances that do not align with the code stipulations and could lead to inconvenience and potential hazards, reinforcing the importance of adhering to the specified requirement.
