ITC 101: Understanding IP Ratings for Electrical Enclosures
Electric and electronic equipment are often exposed to challenging environments where dust, water, or accidental contact can cause failures. To address this, the International Electrotechnical Commission (IEC) established the Ingress Protection (IP) rating system under the IEC 60529 standard. This system provides a clear, standardized method of indicating how well an enclosure protects against solids, liquids, and access to hazardous parts.
