Re: what kind of enclosure
alerto,
Which one of the following typrs of enclosures fits the description of the environment?
NEMA 3 ? Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, and windblown dust; and that will be undamaged by the external formation of ice on the enclosure.
NEMA 3R ? Same as NEMA 3 excluding protection against windblown dust.
And then there are:
NEMA 4 ? Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external formation of ice on the enclosure.
NEMA 4X ? Same as NEMA 4 including protection against corrosion.
