Hi everyone... my understanding is that a typical triplex service drop has an outer cover for weather protection but it is typically not rated as insulation. Is this true for all service drop conductors? I understand that if they are marked with type SE/USE, then, that outside jacket IS insulation but otherwise, it's just for weather protection. Where can I find information that will either confirm what I understand or clarify my knowledge? (NEC, UL, ANSI...?) Thanks everyone!
