The National Equipment Manufacturers Association (NEMA) rating system is primarily used in North America as the national electrical codes mandate that the NEMA rating system is used. The NEMA rating system differs from the IP rating system in that increasing numbers do not signify that the enclosure offers better protection than the number that proceeds it. For example, types 3, 4 and 6 are intended for outdoor use, but type 5 is not. [1] Equipment for off-grid PV systems will fall into ratings 1-5.
