What Is a NEMA 1 Enclosure?

The NEMA rating system is an industry standard, established by the National Electrical Manufacturers Association, that makes it easy to identify an electrical enclosure’s protective qualities. (See our complete guide to NEMA ratings for an in-depth look at the various types of NEMA-rated enclosure types.)

An enclosure with the NEMA 1 rating is designed for indoor use and offers a degree of protection against:

  • Accidental contact with hazardous parts
  • Falling dirt

NEMA 1 enclosures are a common choice for devices that need a tough and resilient enclosure, but don’t necessarily require protection against more severe hazards like rain, sleet, corrosion or windblown dust. However, NEMA 1 boxes also commonly carry more protective ratings that make them suitable for a wider variety of applications and environments.
