Appliances installed outdoors must be both listed and labeled for what type of installation?

Appliances installed outdoors must be both listed and labeled for outdoor installation due to the specific conditions and requirements they face when exposed to the elements. This includes factors such as moisture, temperature variations, and potential exposure to debris, which can significantly affect the safety and functionality of the appliance. Outdoor-rated appliances are designed to withstand these environmental challenges, providing greater durability and performance compared to indoor-rated appliances.

Choosing an appliance that is labeled for outdoor use ensures compliance with safety standards and regulations, which often require that outdoor appliances have appropriate protection against weather-related damage. This designation is crucial both for the safety of the user and to prevent potential hazards, such as electrical shorts or failures caused by inadequate weatherproofing. Therefore, for any installation intended for outdoor use, it is essential that the appliance is clearly marked for outdoor installation.
