Wet locations for 15A and 20A receptacles
NEC® 406.9

The NEC defines wet locations as installations underground or in concrete slabs or masonry in
direct contact with the earth; in locations subject to saturation with water or other liquids, such
as vehicle washing areas; and in unprotected locations exposed to weather.

NEC® article 406.9 (B) (1) requires all 15- and 20-ampere, 125- and 250-volt receptacles installed in a wet
location to have an enclosure that is weatherproof whether or not the plug is inserted. These receptacles
must use a while-in-use cover.

SECTION

Damp locations for receptacles
NEC® 406.9 (A)

A damp location is defined as a location protected from weather and not subject to saturation with
water or other liquids but subject to moderate degrees of moisture. Examples of such locations
include partially protected locations under canopies, marquees, roofed pen porches, and like locations, and
interior locations subject to moderated degrees of moisture, such as basements, barns, and cold storage
buildings.

NEC® article 406.9 (A) requires receptacles installed in damp locations to have an enclosure for the
receptacle that is weatherproof when the receptacle is covered (attachment plug is not inserted and
receptacle cover is closed).

An installation suitable for wet locations shall also be considered suitable for damp locations.
Therefore, all catalog numbers noted for compliance to 406.9 (B)(1) and 406.9 (B)(2) are also suitable

for use in damp locations.
