Weather Resistant Outlets vs Weather Proof Box

gfciweather-resistant

If I use a regular GFCI in a Weather Proof In-Use box does the GFCI have to be the Weather Resistant kind?

Best Answer

Yes. If the receptacle is in a wet or damp location, the receptacle must be a weather-resistant type.

In a damp location, you can use any weatherproof cover. In a wet location, you must use an "extra-duty" cover. "Extra-duty" covers, provide weatherproofing even when a cord is attached to the receptacle.
