Bud Provides a Quick Reference for NEMA Rated Enclosures vs IP Rated Enclosures

A question that we get all the time is what is the difference between a NEMA rated enclosure and an IP rated enclosure. First, a quick explanation of the two systems. NEMA, developed by the National Electrical Manufacturing Association, is used mostly in the US and sets forth an approach that rates the enclosure by its ability to protect the internal components from flying particles and also various types of liquids, both indoor and outdoor. IP, created by the International Electrotechnical Commission, is typically used outside the US and uses a two digit system where the first digit has increasing levels of protection against particles and the second does the same with liquids. Neither group performs tests nor do they certify that products meet these standards but the manufacturer must utilize a testing group, such as UL for NEMA and TUV for IP.
