A while-in-use weatherproof electrical box cover, also known as an in-use cover or bubble cover, is a protective enclosure designed to shield outdoor electrical outlets and switches from environmental elements while allowing them to remain operational. These covers are typically made from durable materials like polycarbonate or metal and feature a hinged or sliding lid that can be securely closed over the outlet or switch.
The primary function of a while-in-use cover is to provide a weather-resistant barrier that prevents moisture, dust, debris, and other contaminants from entering the electrical box, which could otherwise lead to short circuits, corrosion, or electrical hazards. This is particularly important in outdoor settings where outlets are exposed to rain, snow, and other harsh conditions.
Unlike standard flat covers, while-in-use covers are designed to accommodate plugs and cords while the cover is closed. This is achieved through a domed or extended design that provides enough space for the plug to remain connected, ensuring continuous power supply without compromising the protective seal. The cover typically includes a gasket or seal around the edges to enhance its weatherproof capabilities.
These covers are commonly used in residential, commercial, and industrial settings where outdoor electrical access is necessary, such as in gardens, patios, construction sites, and outdoor entertainment areas. They are often required by electrical codes to ensure safety and compliance with regulations.
In summary, a while-in-use weatherproof electrical box cover is an essential safety device that allows outdoor electrical outlets to be used safely and efficiently in various weather conditions, providing both protection and convenience.
