Can an Outdoor Receptacle Feed From the Garage Receptacles

All exterior receptacle outlets need to be covered for protection from rain and moisture. The National Electrical Code (NEC 406.9) separates the requirement into two categories:

1) Damp locations - Where the receptacle is in a location that is protected from beating rain or water runoff, it is considered to be in a damp location and can have a cover that is weatherproof only when a cord is not inserted. A hinged-type cover, like the one shown below, is acceptable for a damp location, but not a wet location.

2) Wet locations - When the location is exposed to beating rain or water runoff (unprotected location) the required cover must also be weatherproof when a cord is inserted. This means a bubble-type or other type cover that offers all-weather protection, even when a cord is plugged in, like in the photo at the top of the page. Newer installations also have a recessed receptacle with a flush weather cover plate. This is also called an "in-use" receptacle cover.

    The hinged-type cover was previously approved for wet locations, but no longer. Also, even in homes built when the hinged-type cover was still approved, the approval was only for temporary use of the receptacle, such as for an electric leaf blower. Any permanently installed cord, like for a sprinkler control panel, requires an in-use receptacle cover.

    Another requirement for exterior receptacles is GFCI-protection, which has been necessary since the 1975 edition of the NEC.
