What Is IP20 Protection?

A rating of “IP20” (pronounced “IP two zero,” not “IP twenty”), denotes protection from solid objects approximately 12mm in size, such as adult fingers; however, it also denotes no protection at all against liquids.

IP (ingress protection) ratings specify how much protection an enclosure, such as a computer case or electrical socket, has against solid objects and liquids getting into the object. The first number denotes protection from solids, and the second denotes protection from liquids. Thus, an object that conducts electricity and has an IP rating of 20 should be kept away from liquids. It may also need to be kept away from children, as they have smaller fingers that may touch exposed electrical parts.
