What requirements must appliances installed in locations other than indoor ones meet?

Appliances installed in locations other than indoor ones must be listed and labeled to ensure they meet the necessary safety and performance standards. "Listed" refers to the product being included in a list of recognized equipment by a standards organization, which verifies that the appliance has been tested and conforms to specific performance and safety standards. "Labeled" indicates that the appliance carries a label or mark provided by the listing agency, communicating critical information about the product, including safety instructions and installation guidelines.

This requirement is crucial for outdoor installations due to increased exposure to environmental factors such as moisture, temperature changes, and UV radiation. Compliance with these requirements ensures that the appliances function safely and effectively in challenging conditions that are not typically encountered indoors. Understanding this helps ensure that installations are not only compliant with regulations but also safe for long-term use in various outdoor environments.
