Please refresh me on this. Does ALL outside outlets have to have an "in use" cover now, and could you give me the code reference? Thanks.. Steve

I have a few questions what is the difference between damp location and wet location? Then what would a covered front porch be considered. I use a regualar weather proof cover( with 2 flaps) on covered areas and in use covers in areas with no coverage(like 12" overhang)

The general practice, assuming that there are no physical barriers in place, is to go to the nearest overhead projection and imagine a 45 degree line, toward the structure. Above this line is considered "damp;" below it "wet." So, if you assume a porch 10 ft deep, with an overhang 8 ft. above the decking, receptacles on the inside wall would be in a 'damp' location.
The same rule can be applied to receptacles directly under the eaves. And, of course, there would be little sense in using a 'bubble' cover for a receptacle that faced 'down.'
Now .... here's the catch .... there is a general requirement that equipment be suitable for the environment in which it is installed. I would use this as a reason to use a "Bell" box in nearly any outdoor location, however it may be sheltered. Why? Insects. I'm tired of trying to remove covers, only to see six furry legs trying to pull the covers back on!  All those little holes in 'normal' boxes make them havens for wasps and spiders.

If the receptacle is in, what is considered a "damp location", a regular weatherproof cover is approved?? This is what I get by reading 406.8 (A) in the 2005 code. So a receptacle that in under a front porch area, if it is not subject to a "beating rain" or "run off", does not require an "in use cover" ??? I have a job that is requiring the receptacles be located on the outside post, under a roofed deck. This is not directly subject to a beating rain,(unless the rain is a blowing rain), but I think I will go ahead and figure in use covers, for the reason that they are using it as an "outside kitchen" and there may be some appliances, such as a small refrigerator, that are left plugged up all the time. Thanks for the comments, Steve...

There are very few instances where you should not use an in-use cover, IMHO. Exceptions, as mentioned above, would be on the underside of an eave (for holiday lighting, etc.) that has virtually no chance of being subjected to direct splash, from rain or any other source (i.e. sprinklers) when a plug is installed.
When in doubt, use an in-use.

Nowadays I like to refer to the NEC as the National Electrical Catalog, since it contains so many new procedures to buy new products.
