What specifications are required for lampholders used in wet locations?

The requirement for lampholders used in wet locations is that they must be weatherproof and rated specifically for wet locations. This specification is essential to ensure safety and compliance with the National Electrical Code (NEC). Lampholders that are designed for wet locations have specific materials and construction that can withstand exposure to moisture without compromising electrical safety or performance. This is particularly important because moisture can lead to corrosion, electrical shorts, and other potential hazards.

Choosing lampholders that are not specifically rated for wet environments can pose significant risks, such as electrical shock or fire hazards. Therefore, it's essential to select products that explicitly state they are suitable for wet locations, adhering to the safety standards outlined in the NEC. Other options presented might suggest different types of protective measures or materials, but they do not fulfill the critical requirement of being rated for wet locations, which ensures adequate protection and safety in environments where moisture is present.
