NEMA Enclosure Types
Since the IEC protection requirements become more stringent with increasing IP character value up through 6, once a NEMA Type rating meets the requirements for an IP designation up through 6, it
Common ratings include NEMA 1 (indoor), NEMA 3R (outdoor rain protection), NEMA 4/4X (watertight and corrosion resistant), NEMA 12 (dust and oil), and NEMA 6P (submersible). NEMA ratings differ from IP ratings in scope and testing methods. An outdoor electrica...
