Listed or labeled equipment for a use shall be installed and used in accordance with ___.

• A. the job specifications
• B. the instructions included in the listing, labeling, or identification
• C. the instructions given by the authority having jurisdiction
• D. the plans

Answer: (B)

Equipment that is listed or labeled has been tested and approved for specific uses, so you install and use it strictly according to the instructions that come with the listing or labeling. Those instructions come from the manufacturer and the testing lab and spell out how the device should be mounted, wired, torqued, and operated, as well as any environmental or location restrictions. Following them keeps the equipment within the conditions it was tested for, preserving safety and code compliance. Deviating from these instructions can void the listing and create unsafe conditions, regardless of other project documents you might be following. While the authority having jurisdiction and project plans may add requirements, the baseline guidance for listed equipment is the listing’s instructions.
