CP protection boxes

This rule allows to indicate the level of protection provided by enclosures for electrical equipment against access to hazardous parts inside the case and against
ingress of solid foreign objects and water. This rule does not consider
protection against the risks of explosion or environmental situations
such as moisture, corrosive fumes, molds or insects.
In any case, the degree of IP protection declared must be ensured
in “ordinary condition of service of equipment.”
