what is tps cable
Thermoplastic-sheathed cable (TPS) consists of an outer sheath of polyvinyl chloride (PVC) insulation (the thermoplastic element) covering a core of one or more conductors of annealed copper.It is the most commonly used type of wiring for residential and light commercial construction in developed countries.t is incorrect to use Romex to refer to NM cable generically, as the Romex name is a trademarked brand of the Southwire Company. In modern products, the color of the NM cable sheath (or jacket) indicates either the gauge of the current carrying conductors within it, or special properties of the sheathing itself.
