The recipe for condensation is simple: water vapour and fluctuating temperatures. In all but the most controlled of environments this means that electrical installations are at risk of water damage caused by condensation forming inside an enclosure. Of course, with proper planning and design it's possible to protect your connections, as Chris Lloyd explains In combating condensation in enclosure applications, it is first important to understand why condensation occurs and which types of electrical installation are most at risk. As we know, condensation describes the changing physical state of water from gas into liquid - typically caused by the gas coming into contact with a colder surface. So, condensation is a risk in any environment where water vapour will be found in the air and where temperature fluctuations occur.
