At Nema Enclosures, we utilize the IEC's standardized International (or Ingress) Protection Code system for measuring enclosures' capabilities. Type 2 Enclosures constructed for indoor. The IEC (International Electrotechnical Commission) and BS 7671 (British Standard for Electrical Installations) both provide essential requirements for electrical installations, including those for fuse boards like garage unit, consumer unit and distribution board. The technical content of IEC publications is kept under constant review by the IEC. Please make sure. IP44 is a widely used ingress protection rating for electrical enclosures and control panels. Defined by the international IEC 60529 standard, the IP rating system helps determine how well a cabinet or box resists the intrusion of solids and liquids. An IP44-rated cabinet is suitable for many.
