Lighting track is not permitted to be installed within a specific zone around a bathtub rim. What are the dimensions of this zone?

The correct answer indicates that lighting track is not permitted to be installed within a zone that extends 3 feet horizontally and 8 feet vertically from the bathtub rim. These dimensions are established to ensure safety and compliance with the National Electrical Code (NEC), which aims to prevent electrical shock hazards in wet locations.

This zone is critical because water sources create conditions where electrical devices could potentially be exposed to splashes or humidity, increasing the risk of contact with water. In residential settings, this regulation helps to protect users from electrical hazards while using bathtubs. As water can conduct electricity, maintaining a safe distance for electrical installations helps reduce the possibility of accidents.

Understanding these specific measurements is important for both compliance with regulations and ensuring the safety of the installation. When installing lighting in close proximity to a bathtub, it is vital to follow these guidelines to avoid installation that could lead to dangerous situations.
