If I may ask a back to basics question. The country specific agency flame ratings for insulated wiring seem to not be harmonized. Some materials such as limited current (signal) interconnect wiring are marked as VW-1 while others are marked with FT-1,2,3,4 or CL-2. VW nomenclature is a UL rating for wiring, while FT-x is a Canadian rating and test method, and CL2 is a NEC rating. Have I left any out? (;^)
Is there such a thing as a cross reference table that indicates which is equivalent (and per application?) ? For example, FT4 = VW-1 = CL2 for vert./horiz. raceway? Inquiring minds...
