NEC Compliance Matters
NEC® Section 406.9 includes different weatherproof enclosure requirements for receptacles in damp and wet locations. Depending on the location and application, the appropriate solution may need to provide protection when the receptacle is not in use or while a plug is connected. Many Leviton Weatherproof Covers & Boxes are designed to support installations that meet applicable NEC® Section 406.9 requirements when properly selected and installed.
Choosing the Right Solution
From standard weatherproof covers to while-in-use options that protect devices while plugged in, selecting the proper cover helps improve durability, safety, and long-term performance. Leviton also offers industrial-grade weatherproof covers for FD box and panel-mount applications, providing flexibility for demanding commercial and industrial environments.
When selecting a weatherproof cover, consider:
- Device type: Match the cover to the installed device, such as a duplex receptacle, GFCI receptacle, Decora® device or toggle switch
- Number of gangs: Select the appropriate cover size and configuration for single-gang, multi-gang, or combination device installations
- Location conditions: Evaluate whether the installation is in a damp or wet location and the level of exposure to rain, moisture, dust, or debris
- In-use requirements: Determine whether the receptacle requires protection only when not in use or while a cord and plug are connected
- Mounting application: Consider whether the installation uses a standard weatherproof box, FD box, or panel-mount configuration
- Code requirements: Verify applicable NEC® requirements and local codes to help ensure the selected solution is appropriate for the installation
