Quick answer

A weather-resistant (WR) receptacle is built to handle damp/exposed conditions, but it is only protected from rain when its cover is closed. A weatherproof "in-use" (bubble) cover keeps an outlet protected for wet locations even while a cord is plugged in. Outdoors, you usually want a WR receptacle and an in-use cover — and outdoor outlets commonly require GFCI protection.

Damp vs wet location (the key distinction)

  • Damp: protected from direct rain (e.g., under a covered porch). A WR receptacle with a standard

closing cover may suit.

  • Wet: exposed to rain/sprinklers, or something stays plugged in. You need an in-use cover.
Safety note: Outdoor receptacles commonly require GFCI protection and may need a permit. Confirm requirements with a licensed electrical contractor and your local code before installing.

What to check before buying

WR rating stamped on the device · cover type (closing vs in-use) · box rating for outdoor use · gasket quality · whether GFCI protection is provided at the device or upstream.
