To be used for a specific application, equipment must be what?

• A. It has been tested and approved for a specific use.
• B. It is guaranteed to be maintenance-free.
• C. It cannot be used in commercial installations.
• D. It is the most expensive option.

Answer: (A)

Equipment must be listed and approved for the specific use it will serve. In practice, this means the equipment has been tested by a recognized lab and carries a listing/ labeling that specifies the exact application, environment, and ratings it is suitable for. Using equipment only within what its listing covers ensures it will perform safely and in accordance with the NEC. If you use it for a purpose or environment it’s not listed for, you’re operating outside what the code requires and you’ve lost the assurance of safety and compliance. The option that states it has been tested and approved for a specific use is the best choice. Maintenance-free, unauthorized commercial restrictions, or higher cost do not define suitability or code compliance.
