Weatherproof electrical boxes and in-use covers protect outdoor outlets, switches, and other wiring devices from rain, moisture, and dust. The NEC and local codes require weatherproof protection for all receptacles installed in wet or damp locations, covering both new construction and retrofit applications.

Standard weatherproof boxes are rated for exterior surface mounting with sealed conduit knockouts and gasketed covers to keep moisture out of wiring connections. In-use covers, sometimes called while-in-use covers, allow a cord to remain plugged in while the cover is closed, maintaining weatherproof protection during active use. These are required by code for outdoor receptacles serving continuous loads such as holiday lighting, landscape equipment, and power tools.

Cover styles include flip-lid, bubble, and horizontal or vertical cord-exit designs to accommodate different outlet and plug orientations. Products carry NEMA 3R, NEMA 4, or WP ratings depending on the exposure level. Stainless steel and UV-stabilized plastic construction options are available for coastal and high-UV installations.
