A light fixture installed over a tub in a mobile home is required to be what?

A light fixture installed over a tub in a mobile home must be enclosed or sealed with a gasket to ensure safety and compliance with electrical codes. This requirement is especially important in wet locations where water exposure is a possibility, such as near a bathtub. Fixtures that are enclosed or sealed help prevent moisture from entering the electrical components, thereby reducing the risk of short circuits, electrical shock, or fire hazards.

While other choices might relate to electrical safety, they do not address the specific concern of moisture exposure as directly as the requirement for sealing. For example, fixtures rated for dry locations wouldn't be suitable for environments where they could be exposed to splashes of water. Similarly, while ground fault protection is essential in wet areas to guard against electrical shock, the immediate requirement of sealing addresses the risk of water itself. In summary, the sealing requirement directly addresses the safety hazards posed by the proximity of electrical fixtures to water.
