  2. 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 ...

  3. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    In the North American electrical industry, conductors thicker than 4/0 AWG are generally identified by the area in thousands of circular mils (kcmil), where 1 kcmil = 0.5067 mm 2. The next wire size thicker than 4/0 has a cross section of 250 kcmil. A circular mil is the area of a wire one mil in diameter. One million circular mils is the area ...

    en.wikipedia.org/wiki/MC4_connector

    MC4 connectors are successors of the MC3 Connectors, which were developed by Multi-Contact in 1996. MC3 is the abbreviation of Multi-Contact and its size 3mm PV connector with 3 mm contact pin. MC3 had certification ratings of (1000VIEC/600V UL) and 30A (10AWG PV Cable). The MC3 connectors were discontinued in 2016.

  5. Ampacity - Wikipedia

    en.wikipedia.org/wiki/Ampacity

    High ambient temperature may reduce the current rating of a conductor. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. A lower rating will apply if multiple conductors are in proximity, since each contributes heat to the others and diminishes the amount of external cooling of the conductors.

    IEC 60055 Paper-insulated metal-sheathed cables for rated voltages up to 18/30 kV (with copper or aluminium conductors and excluding gas-pressure and oil-filled cables) IEC 60059 IEC standard current ratings; IEC 60060 High-voltage test techniques; IEC 60061 Lamp caps and holders together with gauges for the control of interchangeability and safety

  7. IEC 60320 - Wikipedia

    en.wikipedia.org/wiki/IEC_60320

    A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. [1 ...

  8. IEC 60309 - Wikipedia

    en.wikipedia.org/wiki/IEC_60309

    The standard includes preferred current ratings and wire gauges for both International (deemed Series I) and North American (deemed Series II) applications. Series I preferred current ratings (in amps) are: 16, 32, 63, 125, 250, 400, 630 and 800, with wire gauges specified as mm 2 .

  9. DC connector - Wikipedia

    en.wikipedia.org/wiki/DC_connector

    Often pins 1 and 2 will be negative, 3 and 4 positive for a higher current rating. Female connectors are used as supply and male connectors are used on loads. Most battery belts and power supplies output 13.2 V, but equipment can usually handle a range of 11–18 volts to accommodate battery packs of varying voltages and charging while operating.
