MC cables also feature plastic sheathing around the internal wires, while armored cable uses paper. Whether you're replacing old wiring in your home or adding new electrical wires, it's important to choose the right type. If you're unsure which type of electrical wire you need, it's helpful to consult a professional electrician before installing any sort of electrical lines in your home. Armored cable, which you may come across in an older home renovation, is a type of wiring that features a metal jacket around the wires to protect them from damage. One of the purposes of armored cable's metal jacket is to eliminate the need for conduit, as the wire has its protective layer. Physically, an electrical cable is an assembly consisting of one or more conductors with their own insulations and optional screens, individual coverings, assembly protection and protective coverings.

Like armored cables, metal-clad cables feature metal sheathing that offers protection to the wiring, allowing it to be installed in areas where it may be vulnerable to damage.

Metal-clad cables, or MC cables, are very similar to armored cables, yet with some key distinctions. However, unlike armored cables, metal-clad cables feature a full-size designated ground wire, while armored cables rely on a combination of the metal jacket and a thin wire or strip for grounding. In order to work better, some colors have been established for the insulators to better identify their function.The colors of the electrical cable insulation are as follows:- Green and yellow wire: it is the ground wire, with which the ground connection is made.- Blue wire: it is the neutral wire. Additionally, the metal jacket itself is utilized as a ground. For example, in wet locations outdoors, UF wire should always be chosen to ensure that your home's electrical system is protected from the elements. The purpose of this layer is to make the cable look round.- Sheath: performs the function of protecting the cable from external elements. There is no difference between the two wires electrically speaking, but one or both wires will often feature some type of marking to make them more easily traceable over a distance.

The Earth's natural geomagnetic field strength varies over the surface of the planet between 0.035 mT and 0.07 mT (35 μT - 70 μT or 350 mG - 700 mG) while the international standard for continuous exposure is set at 40 mT (400,000 mG or 400 G) for the general public. For intermediate-length lines on the order of 100 kilometres (62 miles), the limit is set by the voltage drop in the line. DC technology is used for greater efficiency over longer distances, typically hundreds of miles. Long-distance communication takes place over undersea communication cables. The amount of power that can be sent over a transmission line varies with the length of the line. Flat connectors on each end allow the wire to connect at two points while taking up a minimal amount of space. Much like "ribbon cable," its signature shape has earned names like "flat cable" and "multi-planar cable." The purpose of this arrangement is to maximize the potential number of wires while minimizing the footprint, which allows for many wires to fit in tight spaces. Ribbon cable is a type of wiring where each wire conductor is attached at its side, creating a flat ribbon-like wire.

Armored cable is often chosen for installation in interior locations that are exposed, which would leave the wiring vulnerable to damage. Copper wires in a cable may be bare, or they may be plated with a thin layer of another metal, most often tin but sometimes gold, silver or some other material. New Scientist and Reuters (May 22, 2007). "Superconducting power line to shore up New York grid". At higher voltages, where more than 2,000 kV exists between conductor and ground, corona discharge losses are so large that they can offset the lower resistive losses in the line conductors. Substation transformers reduce the voltage to a lower level for distribution to customers. These cables are stranded to lower skin effects. You might have seen those thick electric cables that are used to transmit electric current to our homes from the power station. The electrical cables used in offices and homes are: THN, THW, THHW and THWN.What does the color of electrical cables mean?
