What is required for electrical installations in wet locations?

Use of outdoor-rated equipment
Standard receptacles
Conventional switches
Use of only metallic conduit

The correct answer is: Use of outdoor-rated equipment

For electrical installations in wet locations, the use of outdoor-rated equipment is crucial. This requirement ensures that the materials and devices used can withstand the unique challenges posed by moisture and potential water exposure. Outdoor-rated equipment is specifically designed to resist corrosion and function safely even in humid or wet conditions. This includes protective enclosures for electrical boxes, GFCI (Ground Fault Circuit Interrupter) outlets, and other fixtures that can tolerate both water and UV exposure. In contrast, standard receptacles and conventional switches are not necessarily designed to handle wet conditions, and using them could lead to malfunction or safety hazards. Metallic conduit, while possibly effective for some scenarios, does not cover the need for weather-resistant components and might not be ideal for installations frequently exposed to water. Thus, utilizing outdoor-rated equipment addresses the necessary safety and operational standards for installations in wet environments.
