NEMA vs IP Ratings: Which Enclosure Standard You Need
NEMA and IP ratings aren’t interchangeable. NEMA 4X includes corrosion and ice testing that IP66 doesn’t cover. Wrong specifications mean rejected equipment, premature failures, and 25-40% cost overruns. Use NEMA for North American industrial installations. Use IP for international projects. Specify based on actual environmental conditions and regional requirements, not assumed equivalency.
