What type of labeling is required for appliances installed outdoors?

For appliances installed outdoors, the requirement for labeling is that they must be "listed and labeled." This means the appliance has been tested and complies with the safety standards established by recognized testing laboratories. The labeling typically indicates that the appliance is suitable for outdoor use, which is crucial for ensuring safety and performance in potentially harsh environmental conditions.

Listed and labeled appliances provide assurance that they have undergone rigorous testing for their intended application and that they meet specific performance criteria. This label helps installers and users understand that the appliance is designed to withstand various outdoor factors, including moisture, temperature fluctuations, and potential exposure to environmental contaminants.

Other types of labeling, while they may provide helpful information or warnings, do not meet the comprehensive requirements for safety and compliance that "listed and labeled" signifies. This distinction is critical in maintaining industry standards and protecting both users and the integrity of the installed systems.
