TL;DR
A weather-resistant receptacle is an outlet built with corrosion-resistant contacts, UV-stable thermoplastic, and cold-impact tolerance for installation in damp and wet locations, identified by the WR marking on its face. NEC 406.9 requires the rating outdoors, in unenclosed porches, and similar exposures, paired with a cover: weatherproof-while-in-use bubble covers where something stays plugged in, flat flip covers where use is occasional.
What it means
A weather-resistant receptacle is an outlet built with corrosion-resistant contacts, UV-stable thermoplastic, and cold-impact tolerance for installation in damp and wet locations, identified by the WR marking on its face. NEC 406.9 requires the rating outdoors, in unenclosed porches, and similar exposures, paired with a cover: weatherproof-while-in-use bubble covers where something stays plugged in, flat flip covers where use is occasional. Outdoors it is nearly always also a GFCI or GFCI-protected device, and the WR stamp is what distinguishes it from an identical-looking interior outlet that will corrode green within a couple of seasons.
