NEMA Ratings

NEMA ratings are standards set by the National Electrical Manufacturers Association to classify electrical enclosures based on their ability to protect against environmental factors like dust, water, and corrosion. These ratings help determine how well an enclosure can safeguard electrical components in various conditions, such as indoors, outdoors, or in harsh environments. For example, a NEMA 12 enclosure is designed to protect against dust and falling dirt, while a NEMA 4 is suitable for outdoor use and resistant to water and splashing. These ratings ensure safety, durability, and proper functioning of electrical equipment in different settings.
