How does fitting a cable gland affect the IP rating of an enclosure?
Short answer
Fitting a cable gland does not reduce an enclosure's IP rating as long as the gland is correctly chosen and installed. Cable glands are commonly used to maintain high IP ratings and to retain cables securely, but any holes or empty voids left in the enclosure will allow dust or water to enter and will affect the rating. Choose a cable gland whose IP rating matches or exceeds that of the enclosure, and use a sealing ring between the enclosure and the gland to help maintain a high level of protection.
Cable glands are commonly used to maintain high IP ratings for enclosures and to securely retain cables, so fitting one need not reduce the protection level. If you are planning to fit a cable gland yourself, it is important to choose a gland that will maintain the enclosure’s IP rating.
It is also important to remember that the presence of holes or empty voids in enclosures can affect the IP rating, allowing dust or water to enter the housing structure. Using the proper equipment and installation techniques is therefore essential to ensure the IP rating of the enclosure is maintained.
When looking at suitable solutions, take into account that the IP rating of the cable gland should match or be higher than that of the enclosure. Using a sealing ring between the enclosure and the cable gland will also help to maintain a high level of IP rating.
