3M IEC C7 Figure of 8 Eight Mains Power Cable Lead - 3 Metre Long (Black)

Product Information

North American rating agencies ( CSA, NOM-ANCE, and UL) will certify IEC 60320 connectors for higher currents than are specified in the IEC standard itself. In particular, UL will certify: There are 12 IEC connectors by shape; each has a different name for the Male or Female side. For example C7 is male and C8 is female, but both have the same shape connector. Below you can find a list of the IEC connectors we supply, and a diagram of each. The C1 coupler and C2 inlet were commonly used for mains-powered electric shavers. These have largely been supplanted by cordless shavers with rechargeable batteries or corded shavers with an AC adapter.

Commonly known as a "figure-8", "infinity" or "shotgun" connector due to the shape of its cross-section, or less commonly, a Telefunken connector [21] after its originator. There is some public confusion between C13/C14 and C15/C16 couplers, and it is not uncommon for C13/C14 to be informally referred to as "kettle plug" or "kettle lead" (or some local equivalent). We often find that people are unsure of the difference between mains power cables, or what the IEC standards are. To put it simply, the standards define the mechanical, electrical and thermal requirements and safety requirements of power couplers. IEC 60320-2-1: Sewing machine couplers [6] specifies couplers which are not interchangeable with other couplers from IEC 60320, for use with household sewing machines. They are rated no higher than 2.5A and 250V AC.

A cable consisting of a C13 and an E interconnection connector is commonly mislabeled as an "extension cord", as although that is not the intended purpose, it can be used as such. They are also commonly mislabeled as C14 instead of E. IEC 60320-2-2: Interconnection couplers for household and similar equipment. This section was withdrawn in January 2016. The general requirements for these items were incorporated into IEC 60320-1 and the standard sheets were moved to IEC 60320-3. The dimensions and tolerances for connectors, appliance inlets, appliance outlets and plug connectors are given in standard sheets, which are dimensioned drawings showing the features required for safety and interchangeability. Plug connector: "part of the interconnection coupler integral with or intended to be attached to one cord". For use in very-high-temperature settings, such as some stage lighting instruments. Similar to C15/C16, but the top is narrowed to exclude the C15 cord connector.

The C6 inlet is used on laptop power supplies and portable projectors, as well as on some desktop computers, some LCD monitors and recent LCD televisions from LG. One arbitrarily chosen example of a 1500W PSU with a C14 input is the Enermax MAXREVO 1500 W 80+ Gold. It manages to fit within the 15A input current limit because of its 80 Plus gold efficiency. Also known as the “Figure-8” or “Shotgun” connector, very widely used on an array of devices such as TVs, Blu-ray players, and laptop chargers. This is polarised. There is an un-polarised version of the C7 that has a flat edge on one side of the figure-8 shape. The C7 connector is typically used on a mains cable; the C8 connector is used on the device / power supply. View the range of Lindy IEC C7 mains cables here. IEC 60320-3: Standard sheets and gauges. [4] First published October 31, 2014, this part initially included the standard sheets for both appliance couplers and interconnection couplers. In a 2018 amendment, the standard sheets for the IP couplers defined by 60320-2-3 were added. [9] For appliance couplers the various coupler outlines are designated using a combination of letters and numbers, e.g., "C14". The connector supplies power to the appliance inlet. The appliance inlet is designated by the even number one greater than the number assigned to the connector, so a C1 connector mates with a C2 inlet, and a C15A mates with a C16A. Interconnection couplers have single letter designators, e.g., "F". They consist of a plug connector and an appliance outlet. The plug connector is the part integral with, or intended to be attached to, the cord, and the appliance outlet is the part integrated with or incorporated into the appliance or equipment or intended to be fixed to it, and from which the supply is obtained.The C13/C14 connector and inlet combination are used in a wide variety of electronic equipment ranging from computer components like the power supply, monitors, printers and other peripherals to video game consoles, instrument amplifiers, professional audio equipment and virtually all professional video equipment. An early example of a product that uses this connector is the Apple II. A power cord with a suitable power plug (for the locality where the appliance is being used) on one end and a C13 connector (connecting to the appliance) on the other is commonly called an IEC cord. a b "IEC 60320-3:2014+AMD1:2018+AMD2:2022 CSV | IEC Webstore". webstore.iec.ch . Retrieved 2023-05-13. Pin temperature is measured where the pin projects from the engagement surface. The maximum permitted pin temperatures, are 70°C (158°F), 120°C (248°F), and 155°C (311°F), respectively (the higher temperatures are not applicable to interconnection couplers). The pin temperature is determined by the design of the appliance, and its interior temperature, rather than by its ambient temperature. Typical applications with increased pin temperatures include appliances with heating coils such as ovens or electric grills. It is generally possible to use a connector with a higher rated temperature with a lower rated appliance inlet, but the keying feature of the inlet prevents use of a connector with a lower temperature rating.

In addition to the connections within the standards, as mentioned, there are possible combinations between appliance couplers and IEC interconnection couplers. Fitted with a flexible cord, the components become interconnection cords to be used for connecting appliances or for extending other interconnection cords or power supply cords.

The mains appliance couplers are all engineered to connect an appliance via a power cord to mains power.

The IBM Wheelwriter series of electronic typewriters are one common application. Three-wire cords with C13 connectors, which are easier to find, are sometimes used in place of the two-wire cords for replacement. In this case, the ground wire will not be connected. The C7 is a 2 pin power connector in the shape of a figure 8, some equipment uses keyed or polarised versions but the standard figure 8 connector will fit these. Angled Figure 8 Power Cables are also available where space is at a premium such as mounting TVs flat on a wall. IEC 60320-2-3: Couplers with a degree of protection higher than IPX0 [7] specifies couplers with some degree of liquid ingress protection (IP). In its second edition published in 2018, the standard sheets were moved to IEC 60320-3.IEC - SC 23G Dashboard > Projects / Publications: Work programme, Publications, Stability Dates, Project files". www.iec.ch .
