410.6 Listing Required. All luminaires and lampholders
shall be listed.
Listed. Equipment, materials, or services included in a list
published by an organization that is acceptable to the authority
having jurisdiction and concerned with evaluation
of products or services, that maintains periodic inspection
of production of listed equipment or materials or periodic
evaluation of services, and whose listing states that either
the equipment, material, or service meets appropriate designated
standards or has been tested and found suitable for
a specified purpose.
Informational Note: The means for identifying listed
equipment may vary for each organization concerned with
product evaluation, some of which do not recognize equipment
as listed unless it is also labeled. Use of the system
employed by the listing organization allows the authority
having jurisdiction to identify a listed product.
