We are a small (but growing) jurisdiction with a lot of specialty contractors jumping on the growth bandwagon. There are a few 'Sign Companies' in town that are manufacturing and installing all types of signs, with and without electrical.
My question is, do we need to require that these electrical signs (backlit with flourescents), enclosures and electrical to be UL listed and do they need to provide us with the appropriate UL listing to be used? (600.3)
OR---Does the shop itself need to be a 'UL shop', with their own UL certification......OR---Do we need to require that they have third party certification and/or listing of their assembly?
We are still on the learning curve here and would appreciate some enlightenment!!
