Issue
What NEMA or IP rating is a specific product?
Environment
All devices
Cause
Is a product protected against water and access by foreign objects?
Resolution
The Degrees Of Protection document details both the IP rating and NEMA Enclosure charts.
The IP rating is made up of 2 digits, the first is the level of protection to foreign objects, the second is the level of protection to water.
If a product does not specify any rating for water ingress in it's datasheet then the the second digit will be 0.
The first digit relates to the size of a foreign object that can be inserted into the product.
Typically many Buildings products will not allow the insertion of a finger (12.5mm approx' 1/2") and offer no water protection, so they would be rated as IP20,
however it would be IP10 should they have holes of up to 50mm (approx' 2").
