When selecting between single core and multi core wires, knowing the application of each wire is important. Single core wires are often placed in areas where flexibility and movement is crucial like in house wiring and lesser jobs. On the other hand, multi core wires are engineered to bear more demanding applications, for example, in industries with high current conditions and where the signal loss need to be at a bare minimum. Different wires serve different purposes while taking into consideration a wide range of conditions and market needs as well as unique benefits of each wire.
