What is required for the installation of luminaires in wet locations?

The installation of luminaires in wet locations necessitates a combination of features to ensure safety and functionality. Using waterproof enclosures is crucial as it protects the electrical components from moisture and prevents short circuits or corrosion, which are common issues in wet environments. Non-metallic fixtures are often preferred since they can be more resistant to rust and corrosion compared to metal options, further enhancing durability in these conditions.

Special wiring methods may also be required to prevent moisture-related damage to the electrical system. These methods can include using water-resistant conduit or ensuring that connections are properly sealed to avoid any risk of water ingress.

Considering all these requirements together guarantees that luminaires installed in wet locations can function safely over time, hence the correct answer encompasses all the necessary components for such installations.
