What is the definition of equipment that features an identifying mark from an approved product evaluation organization?

The term that best describes equipment marked by an approved product evaluation organization is "Labeled." In the context of the National Electrical Code (NEC), "labeled" refers to equipment that has undergone testing and has been found to meet specific safety standards set by a recognized testing laboratory. This marking provides assurance to users that the equipment complies with the necessary safety and performance requirements.

Each of the other terms has distinct meanings within the electrical industry. "Listed" refers to equipment that has been evaluated and found suitable for its intended use according to the standards set up by a recognized organization. "Certified" generally indicates that a product has met specific criteria laid out by a certifying body but is not interchangeable with "labeled." "Identified" usually refers to equipment that is recognized as suitable for a particular purpose, but it does not specifically include the element of approval from an evaluation organization.

In summary, "Labeled" is the term that reflects the identification and approval process by a recognized organization, ensuring compliance with safety and performance standards.
