NM cable was invented by the Romex company in 1922 and was first described and listed by the NEC (National Electrical Code) in 1926, but it did not come into prevalent use until the early 1960s when plastics replaced woven rayon as the material used for the outer sheathing. NM means "nonmetallic", referring to the outer sheathing; the conductors are still metallic. , chemical and acidic effect may damage the cables and wires. Generally, this type differs from a metallic sheathed cable, which features a metal coil that protects internal wiring. PVC cables offer higher flexibility in all . The phase or line conductors are looped either in switchboard or box and neutrals are looped either in switchboard or from light or fan. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? Very clear topic explanation.

Because fiber allows one mode of light to propagate, light pulses put on the fiber keep their shape much longer. PVC is very resistant to corrosion, impact, abrasion, weathering and even chemical corrosion. It is also suggested by some that the resistance of conductors should be monitored to ascertain that conductors are not being over dissolved with their resistance thereby increasing. Space factor have to be put into consideration. With cables where the current-carrying conductors are of a large cross sectional area (CSA), the protective earth conductor may be smaller, with a lower continuous current carrying capacity. Stanmore, A thermoplastic-sheathed cable(TPS) consists of a toughened outer sheath of polyvinyl chloride(PVC) thermoplastic, covering one or more individual annealedcopper conductors, themselves insulated with PVC. 3 - What Are The Advantages and Disadvantages of PVC Test Lead Cable?
