Europe IEC specifications 144 & 529 define the degree of protection provided electrical enclosures to safeguard personnel against electric shock and equipment within the enclosure from environmental contamination such as entry of water.
This is expressed by the letters IP followed by two numerals.
In the USA, NEMA and UL have established a rating system for enclosures which provided for different levels of protection. A direct comparison between IEC and NEMA is not possible but the following table gives an approximate guide. |
