  2. Aluminum building wiring - Wikipedia

    en.wikipedia.org/wiki/Aluminum_building_wiring

    Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Aluminum provides a better conductivity-to-weight ratio than copper, and therefore is also used for wiring power grids , including overhead power transmission lines and local power distribution lines , as well ...

  3. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    Manufacturers of wire formerly had proprietary wire gauge systems; the development of standardized wire gauges rationalized selection of wire for a particular purpose. While the AWG is essentially identical to the Brown & Sharpe (B&S) sheet metal gauge, the B&S gauge was designed for use with sheet metals as its name suggests.

  4. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    Installing electrical wiring by "chasing" grooves into the masonry structure of the walls of a building. Materials for wiring interior electrical systems in buildings vary depending on: Intended use and amount of power demand on the circuit; Type of occupancy and size of the building; National and local regulations

  5. IEC 60228 - Wikipedia

    en.wikipedia.org/wiki/IEC_60228

    Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

  6. Electrical wiring in North America - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring_in_North...

    The common colors are black, red, blue, brown, yellow, and orange (high-leg delta) insulated wire, sometimes other colors. Specific exceptions apply, such as a cable running to a switch and back (known as a traveler) where the white wire will be the hot wire feeding that switch.

  7. 20-pair colour code (Australia) - Wikipedia

    en.wikipedia.org/wiki/20-pair_colour_code...

    The 20-pair colour code is a colour code used in Australia to identify individual conductors in a kind of electrical telecommunication wiring for indoor use, known as twisted pair cables. The colours are applied to the insulation that covers each conductor.

  8. IEC 60446 - Wikipedia

    en.wikipedia.org/wiki/IEC_60446

    The international standard IEC 60446 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors was a standard published by the International Electrotechnical Commission (IEC) that defined basic safety principles for identifying electrical conductors by colours or numerals, for example in ...

  9. ANSI/TIA-568 - Wikipedia

    en.wikipedia.org/wiki/ANSI/TIA-568

    The colors of the wire pairs in the cable, in order, are blue (for pair 1), orange, green, and brown (for pair 4). Each pair consists of one conductor of solid color and a second conductor, which is white with a stripe of the other color. The difference between the T568A and T568B pinouts is that the orange and green wire pairs are exchanged.
