NEMA Rating
NEMA Rating
(OP)
I have to specify electrical equipment (like panelboard, light fixtures, etc) in an airport-hangar. The hangar has walls and roof but the problem is that it has a very large door from which the planes will come in and go out. In addition to this large door, there are two small doors as well.
I have a feeling that equipment inside the hangar should be Nema-4 due to these doors.
So should the electrical equipment (panelboard, light fixtures, etc) in hangar be rated NEMA 1, or NEMA 3R, or NEMA 4? Thanks for help

RE: NEMA Rating
Light fixtures by the way are not usually NEMA rated, they are usually just "Indoor", "Outdoor", or "Wet Location" listed. So in that case because of the chance of occasional wind blown rain exposure, I would just specify outdoor.
All this is irrespective of any necessary hazardous environmental location issues of course.
