Weatherproof Enclosure – NEMA/IP-rated housing protecting internal components 2. In order to ensure that these distribution boxes can effectively prevent the intrusion of moisture and dust, international standards for protection levels (IP. NEMA enclosure ratings describe how different enclosure types protect against dust, water, corrosion, oil, and hazardous environments. This guide explains the main NEMA types, how they compare with IP ratings, and how to choose the right enclosure. Contact us for custom solutions!.
