What is a while-in-use weatherproof electrical receptacle outlet cover?

Wednesday, June 20, 2018

A while-in-use receptacle cover, as shown above, is different from a regular weatherproof cover, like the one shown below, in that it allows a cord to be plugged into it while still remaining resistant to water intrusion. It is often referred to simply as an “in-use” cover. They usually have a bubble-like front, with openings for a cord to exit through the bottom, so that an appliance cord can be permanently installed and the receptacle will still remain weather-resistant. A regular weatherproof cover is designed for a cord to be temporarily plugged-in, and it  is only weather resistant when not in use.

    When a cord for a permanently installed exterior appliance like a sprinkler system control panel is plugged into a regular waterproof cover and the hinged cover is open, it is no longer weather resistant. This is called out by a home inspectors as an “an unattended cord at an exterior receptacle without an in-use cover.”
