Domestic Audio, video, radio equipment and double insulated power supplies. There are also a variety of splitter blocks, splitter cables, and similar devices available. Wikimedia Commons has media related to IEC Type J outlets are used in a similar way.
They have a variety of common uses including connecting power between older PCs and their monitors, extending existing power cords, connecting to type F outlets strips commonly used with rack-mount gear to save space and for international 60320 and connecting computer equipment to the output of a uninterruptible power supply UPS. C3, C4, C11 and C12 standard sheets are no longer [ when? Very common for power distribution on computer and instrument equipment racks, used to be common as a means of connecting power from a PC to a monitor.
The pin temperature is determined by the design of the 602230, and its interior temperature, rather than by its ambient temperature.
The standards define the mechanical, electrical and thermal requirements and safety goals of power couplers. IEC cords are used to power many pieces of electronic equipment, including computers, instrument amplifiers idc, professional audio equipment and virtually all professional video equipment. This page was last edited on 10 Decemberat Appliance manufacturing may be simplified by mounting an appliance coupler directly on the printed circuit board.
Sheet 27 shows details for screw terminals, where the wire is held by wrapping it around the head of a screw. Some desktop computers provide both a C14 inlet lower and a type F outlet upper for powering the monitor. Views Read Edit View history. Kec appliance with a permanently-attached plug for use in one country cannot be readily sold in another which uses an incompatible wall socket; this requires keeping track of variations throughout the product’s life cycle from assembly and testing to shipping and repairs.

In other projects Wikimedia Commons. Unpolarized C7 connectors can be inserted into the polarized inlets; however, doing so might be a safety risk if the device is designed for polarized power. Unlike IEC connectors, they are not coded for voltage; users must ensure that the voltage rating of the equipment is compatible with the mains supply. It is rectangular and has pins parallel to the long axis of the coupler face. This is the Australian version of the IEC standard with national iex shown.
The C13 connector and C14 inlet are commonly found on computers, servers, routers, and switches. Couplers described under these standards have standardized current and temperature ratings. It also defines an interconnection cord set as an “assembly consisting of one cable or cord fitted with one plug connector and one connector, intended for the interconnection between two electrical appliances”.
Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors. These have largely been supplanted by cordless 6020 with rechargeable batteries or corded shavers which use an AC adapter.
A C8B inlet type is defined by 602230 standard, for use by dual-voltage appliances; it has three pins, and can hold a C7 connector in either of two positions, allowing the user to select voltage by choosing the position the connector is inserted.
Most desktop computers use the C14 inlet to attach the power cord to the power isc, as do many instrument amplifiersmonitors, printers and other peripherals. Appliances can be used in another country easily, with a simple change of iwc power supply cord including a connector and a country-specific plug.
Pin temperature is measured where the pin projects from the engagement surface. The C6 inlet is used on laptop power supplies and portable projectors, as well as on some desktop computers and recent LCD televisions from LG. 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.
Power cord sets utilizing a C13 connector and a C14 plug are commonplace in data uec to provide power from a PDU Power Distribution Unit to a server. Commonly referred to as a “figure of 8” in the UK.
For use in high temperature settings for example, electric kettle, computer networking closets. Common on Enterprise-class servers, UPSs and datacenter rack-mounted power distribution units.
BS EN IEC 60230:2018
Further sub-parts of IEC focus on special topics such as protection ratings and appliance specific requirements. Three wire cords with C13 connectors, which are easier to find, are sometimes used in place of the two wire cords for replacement.
Selection of a coupler depends in part on the IEC appliance classes. Typical applications with increased pin temperatures include appliances with heating coils such as ovens or electric grills. The shape and dimensions of appliance inlets and connectors are coordinated so that a connector with lower current rating, temperature rating, or polarization cannot be inserted into an appliance inlet that requires higher ratings.
In addition to the connections within the standards, as mentioned, there are possible combinations between appliance couplers and IEC interconnection couplers. In this case, the ground wire will not be connected.
Apple uses a modified version of this connector, with the receptacle having a proprietary pin that secures the adapter in place and provides grounding. The power supply cord can be replaced easily if damaged, because it is a standardized part that can be unplugged and re-inserted.
A cord which is fitted with non-rewireable usually moulded connectors at both ends is termed a cord set. Use British English Oxford spelling from December All articles with vague or ambiguous time Vague or ambiguous time from April Commons category link is on Wikidata.
The dimensions and tolerances for connectors and appliance inlets are given in standard sheets, which are dimensioned drawings showing the features required for safety and interchangeability. A similar but polarized connector has been made, but is not part of the standard.
For example, an electric kettle cord can be used to power a computer, but an unmodified computer cord cannot be used to power a kettle. Commonly known as a figure-8 or shotgun connector due to the shape of its cross-section, or less commonly, a Telefunken connector  after its originator.
For appliance couplers this consists of the letter “C” followed by a number, where the standard sheet for the appliance inlet is 1 higher than the sheet for the corresponding cable connector. Appliance couplers enable the use of standard inlets and country-specific cord sets which allow manufacturers to produce the same appliance for many markets, where only the cord set has to be changed for a particular market.
