NEMA enclosure NEMA definition type no. IEC enclosure class 1 NEMA/IEC Enclosure Ratings. Conversion of NEMA type classifications to IEC classification designation (IP ratings) Note: NEMA standards meet or exceed IEC standards; therefore, the conversion does not work in the opposite direction. There are two widely used standards for enclosure ratings. Nema enclosure ratings were created as the national standard for enclosures in the United States.

NEMA enclosure ratings are similar to IEC IP Codes and can offer the same protections, but cannot be mapped directly.

IEC devices are safe to the user, while NEMA devices require safety covers. Despite these significant differences, there are still some common misunderstandings that need to be debunked. NEMA enclosure ratings are similar to IEC IP Codes and can offer the same protections, but cannot be mapped directly. See IP Codes & NEMA.

IEC refers to its enclosure designations as “degrees of protection,” and gives ratings based on a two-digit numbering scheme.
