Thomas Betts DCCU-BR Weatherproof Electrical Box Cover

Product Description

The THOMAS BETTS DCCU-BR is a zinc weatherproof electrical box cover designed to protect outdoor and exposed receptacle installations from moisture, dust, and environmental contaminants. It ships with two adapter plates that allow fitment across a range of standard electrical box configurations. The cover accommodates a single receptacle opening up to 1-9/16 inches, making it suitable for in-use cover applications where a plug or cord must remain inserted while the cover is closed. Licensed electricians and maintenance technicians install this cover as part of NEC-compliant outdoor or damp-location wiring setups.

This cover is used in residential and light commercial electrical installations where a receptacle is mounted in an exposed or semi-exposed location, such as exterior walls, covered patios, garages, pool decks, and similar environments. The included adapter plates extend compatibility to different box configurations, reducing the need for additional hardware. It is appropriate for both new construction and retrofit work where existing receptacle boxes require weatherproof protection.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for damp or wet locations. De-energize the circuit at the breaker and verify with a non-contact voltage tester before beginning work. Secure the cover firmly to the box using the appropriate fasteners to maintain the weatherproof seal. Do not over-tighten fasteners on the zinc body, as this may crack the material or compromise the gasket seal.
