A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads and to carry electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Standard sizes are determined by various wire gauges. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multistranded wire', which is more correctly termed a wire rope in mechanics, or a cable in electricity.continue..
Most electrical wire is covered in a rubber or plastic coating called insulation. What is the purpose of having this ïnsulation" covering the metal wire? In the early days of electrical wiring, wires used to be insulated with cotton. This is no longer accepted practice. Explain why. Electrical wire is often rated according to its cross-sectional diameter by a gauge scale. Which is the larger-diameter wire size, 14 gauge or 8 gauge? continue..
Electrical wiring can be understood as insulated conductors that carry electricity and the associated devices. This article aims at making you understand the basics of electrical wiring along with the types of electrical wires. After reading it, you will be able to understand as to what all electrical wires do and which type is best for what purpose. This information about working of electrical wires types is useful in general monitoring of home home electrical system, especially if you are planning to build or remodel home.continue..
American wire gauge (AWG), also known as the Brown & Sharpe wire gauge, is an outdated, standardized wire gauge system used since 1857 predominantly in the United States and Canada for the diameters of round, solid, nonferrous, electrically conducting wire.[1] Instead of stating the wire diameter or cross-sectional area, it is based on the 19th century historic wire-drawing manufacturing processes. The cross-sectional area of a wire is an important factor for determining its current-carrying capacity. continue..
In Australia, We use a somewhat confusing mixed colour coding system. Our 'equipment' wiring and our 'installation' wiring (i.e. the wiring behind the power-point/wall) colour codes are different.We use an European system for our equipment wiring, but we use an old British-ish system for our installation wiring. To complicate things a little, our equipment wiring standard changed a few decades ago, but the equipment wired to the old standard is still common. It is important to be aware that the colour codes have changed over the years, and to also be aware that some equipment that has been imported may use different colour codes. If in doubt, consult the manufacturer of the equipment.To help provide a summary of the common colour code I have produced to following:continue..

This calculator requires the use of Javascript enabled and capable browsers. The purpose of the calculator is to determine the size of the conductor wire in a circuit of a given distance with a given amperage load. Select the type conductor wire material, the circuit voltage and the phase of the circuit. Enter the total amperage on the circuit; also enter one half of the total length of the circuit. A sample of 120 volts, single phase, copper wire, 144 feet (one half of a 288 foot circuit) with 10 amps load on it yields a number 10 awg wire size. Our calculator yields results that are within code in most locations however we advise you to check your local electrical code. Since we have tried to consider safety as our primary factor, any marginal decision factors are toward the safe side. We allow a maximum voltage drop of about 3% before the wire specification increases. If you need to calculate actual voltage drop, you might want to consider using our voltage drop calculator for both wire circuits and circuit boards, AC and DC. continue..
