What is the answer punchline algebra 15.1 why dose a chicken coop have only two doors? With the use of additives and fillers silicone rubber has become a popular insulation material as it is generally non-reactive, stable and resistant to extreme environments. 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. Unfortunately, now that we know much more about pollution and environmental concerns PVC is often referred to as the poison plastic due to the toxins it can release during manufacture, when exposed to fire, or decomposed in landfills. Also available in smaller conductor sizes are versions containing three current-carrying conductors and a circuit protective (earth) conductor. Sometimes known as "Romex," named for one of the common brand names, NM cable is a flexible electrical cable that features an outer plastic sheathing that protects two or more insulated conductors, as well as a bare copper ground wire. Although PVC will burn when exposed to fire, it is self-extinguishing - if the source of ignition is taken away, it will not continue burning.
