What kind of rating must boxes installed in wet locations have?

Boxes installed in wet locations must have a rating that indicates they are specifically designed and tested for such environments. This means that they must be listed for use in wet locations, ensuring they can withstand moisture exposure without compromising safety or functionality. This rating indicates that the boxes can resist water ingress, which is crucial to prevent electrical hazards, equipment failure, or damage in areas prone to wet conditions. The "listed for use in wet locations" designation comes from adherence to certain industry standards and testing, ensuring that the boxes are suitable for outdoor or damp areas.
