410.110. Listing of Decorative Lighting

XVI. Decorative Lighting and Similar Accessories

Decorative lighting is now required to be listed for the purpose.

Decorative lighting, which can be used for a period of up to 90 days [590.3(B)], must be listed for the purpose. Figure 410-8

Author’s Comment: Faulty or inadequate decorative lighting causes the majority of Christmas tree fires and UL recently developed UL 588, Standard for Seasonal and Holiday Decorative Products to address this problem.

  • However, what I have found is that decorative Christmas lighting that uses 120 volt lamps undergoes less breakage of lamps and filaments and less wear and tear on the cords if it is left up year round. The last installation I did was a commercial application where I uses communication bridle rings to support the light strings.

    NEC does not account for the matter that handling stresses also put wear and tear on this kind of lighting equipment.

    The rooftop electrical receptacles are connected to a lighting controller such that we can completely turn them off, run them continuously, or run off of the lighting controller.
