exactly,
I mean there must be a point to which the disconnect can be taken inside from the edge of a garage door and be considered inside the building.
NEC 312.1 Scope.
This article covers the installation and construction specifications of cabinets, cutout boxes, and meter socket enclosures.
I. Installation
312.2 Damp, Wet, or Hazardous (Classified) Locations.
(A) Damp and Wet Locations. In damp or wet locations, surface-type enclosures within the scope of this article shall be placed or equipped so as to prevent moisture or water from entering and accumulating within the cabinet or cutout box, and shall be mounted so there is at least 6 mm (1/4 in.) airspace between the enclosure and the wall or other supporting surface. Enclosures installed in wet locations shall be weatherproof.
See , the boss does not want to buy an nema 3. The nema 1 has already been punched, nonreturnable.
If money was avalid code term, your boss would have a leg to stand on! The code makes no references to costs of material. The code is based on the NFPA which is about Life Safety.
I just said to ask the inspector, it an interpretation of the nec. .
No interpretation is necessary!
I just dont like it when somebody says. Oh, its code (in the nec) that the disco must be 6' in from the edge of the overhang. And in fact that does not even exist in the code. I like things black and white and if its not so, I identify it as such. Some electricians speak with such confidence when they are really full of it. -
Here is the "black and white".
The code is clear. One must simply read it.
If you do not have a copy, you can buy one or borrow one from your library. Then you will not be dependent on "some electricians" like me and others that actually know the code.
NEC 2002 100 Definitions
Identified (as applied to equipment). Recognizable as suitable for the specific purpose, function, use, environment, application, and so forth, where described in a particular Code requirement.
NEC 2002 100 Definitions
Location, Damp. Locations 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 open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as some basements, some barns, and some cold-storage warehouses.
From UL White Book
Enclosure Type Number Provides a Degree of Protection Against the Following Environmental Conditions*
1 Indoor use
2 Indoor use, limited amounts of falling water
3R Outdoor use, undamaged by the formation of ice on the enclosure**
3 Same as 3R plus windblown dust
3S Same as 3R plus windblown dust; external mechanisms remain operable while ice laden
4 Outdoor use, splashing water, windblown dust, hose-directed water, undamaged by the formation of ice on the enclosure**
4X Same as 4 plus resists corrosion
5 Indoor use to provide a degree of protection against settling airborne dust, falling dirt, and dripping noncorrosive liquids.
You will have to decide which enclosure type would be acceptable for your condition.
I hope this helps!
