Does a UL Listed electric sign require further inspection in the field?
Large signs do. Electric signs so large that shipment in one carton or fully assembled is impractical may be divided into sections. Each major subassembly bears an “Electric Sign Section” Listing Mark. Sign faces, trim and mounting hardware are not considered major subassemblies. Each sign has suitable installation instructions describing or illustrating the proper assembly, mounting and connection of sign sections. The acceptability of the assembled sections in the field, interconnections between sections and the connections to a branch circuit rests with the local authority having jurisdiction.
