Example 1: An enclosure is rated NEMA 3X. What level of protection does it offer and can it be used indoors?

  • A NEMA rating of 3 signifies that it is protected against falling dirt and windblown dust, against weather hazards such as rain, sleet and snow, and is undamaged by the formation of ice. A rating of X means that it carries additional protection against corrosion from salt water.
  • Its ratings exceed what is needed for indoor installation, therefore it is acceptable to use.
