Damp Rated GFI ?

[flashlight]

Ok, so I was installing a gfi in an outdoor box w/ an outdoor in-use cover, all of which I had ordered from a local respectable supply house, when I notice a small sticker on the GFI (leviton btw) : Not to be used in wet or damp conditions. In wet or damp conditions use a suitably rated device.



1) Isn't that arguably what a gfi is for ? I know, there are other conditions, but...

2) If I try to follow that mfr. guideline in that warning, can I consider my outdoor box w/ bubble cover not damp or wet conditions ? It's not wet outside unless it rains, and even then you have that nice cover....

3) I called supply house and said I ordered outdoor boxes, receptacles, and covers and told them about sticker. They told me this was the 1st they had heard this.

Starting with the 2008 NEC

406.8 Receptacles in Damp or Wet Locations.

(A) Damp Locations. A receptacle installed outdoors in a
location protected from the weather or in other damp locations
shall have an enclosure for the receptacle that is
weatherproof when the receptacle is covered (attachment
plug cap not inserted and receptacle covers closed).
An installation suitable for wet locations shall also be
considered suitable for damp locations.

A receptacle shall be considered to be in a location
protected from the weather where located under roofed
open porches, canopies, marquees, and the like, and will
not be subjected to a beating rain or water runoff. All 15-
and 20-ampere, 125- and 250-volt nonlocking receptacles
shall be a listed weather-resistant type.

Don't forget at dwelling units they must also be tamper resistant.

406.11 Tamper-Resistant Receptacles in Dwelling
Units. In all areas specified in 210.52, all 125-volt, 15-
and 20-ampere receptacles shall be listed tamper resistant
receptacles.
