The installation of track lighting near a bathtub must adhere to safety standards to prevent electrical hazards. The correct guideline dictates that fixtures should be installed at least 3 feet horizontally and 8 feet vertically from the edge of the bathtub. This requirement is grounded in the National Electrical Code (NEC), which aims to protect individuals from electrical shock in wet areas.

The horizontal distance of 3 feet helps mitigate the risks of water splashes reaching the lighting fixtures. The 8-foot vertical requirement is particularly important to ensure that the electrical components are far enough away from the potential for condensation and moisture that is present in a bathroom environment, especially near a bathtub. This distance reduces the likelihood of water coming into contact with electrical components, which could cause short circuits or expose users to dangerous voltage levels.

In summary, the specified distances provide a safety buffer to protect both the electrical system and individuals using the bathtub, ensuring compliance with established safety regulations.
