The code reads:
110.3(B) Installation and Use.
Equipment that is listed, labeled, or both, or identified for a use shall be installed and used in accordance with any instructions included in the listing, labeling, or identification.
Informational Note:
The installation and use instructions may be provided in the form of printed material, quick response (QR) code, or the address on the internet where users can download the required instructions.
What it means:
Manufacturers’ listing and labeling installation instructions must be followed, even if the equipment itself is not required to be listed. For example, 210.52 permits permanently installed electric baseboard heaters to be equipped with receptacle outlets that meet the requirements for the wall space utilized by such heaters. The installation instructions for permanent baseboard heaters indicate that the heaters should not be mounted beneath a receptacle. In dwelling units, the use of low-density heating units more than 12 feet in length is common. Therefore, to meet the requirements of 210.52(A) and the installation instructions, a receptacle must either be part of the heating unit or be installed in the floor close to the wall but not above the heating unit. The Informational Note to 210.52 provides specific details.
Listing and labeling are the most common methods of establishing suitability. This section does not require listing or labeling of equipment. Before approving the installation, the AHJ may require evidence of compliance with 110.3.
Some sections do require listed or labeled equipment. For example, 250.8 specifies “listed pressure connectors . . . pressure connectors listed as grounding and bonding equipment [or] . . . other listed means” as connection methods for grounding and bonding conductors.
Listing organizations typically require the use of their listing mark on the equipment as the means of determining if the product is listed. Where it is impractical to have the listing mark on the equipment, the listing organization usually requires that the listing mark be on the smallest unit container in which the product is packaged. Since 110.3(B) requires compliance with the listing requirements, the appropriate certification mark is required if that is a requirement of the listing entity.
