Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors. Appliance manufacturing may be simplified by mounting an appliance coupler directly on the printed circuit board. Iecc couplers enable the use of standard inlets and country-specific cord sets which allow manufacturers to produce the same appliance 62030 many markets, where only the cord set has to be changed for a particular market.
This coupler is used for some IT applications where higher currents are required, as for instance, on high-power workstations and servers, uninterruptible power suppliespower distribution unitslarge network routers, switches, blade enclosuresand similar equipment. Retrieved 29 June It is generally possible to use a connector with a higher rated temperature with a lower rated 6020 inlet, but the keying feature of the inlet prevents use of a connector with a lower temperature rating.
A C18 inlet will accept a C13 connector but a C14 inlet will not accept a C17 connector.
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. Three wire cords with C13 connectors, which are easier to find, are sometimes used in place of the two wire cords for replacement. Power cord sets utilizing a C13 connector and a C14 plug are commonplace in data centers to provide power from a PDU Power Distribution Unit to a server. 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.
There are also a variety of splitter blocks, splitter cables, and similar devices available. Was also used heavily on Marantz Hifi equipment in the s and s. Colored power cables are used to color code installations.
This connector can also be found on high current medical equipment. For other uses, see IEC connector disambiguation.

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.
It is rectangular and has pins parallel to the long axis of the coupler face. 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.
Gender references for connectors actually refer only to the contacts, not the complete connectors.
BS EN IEC 60230:2018
A cord which is fitted with non-rewireable usually moulded connectors at both ends is termed a cord set. Although the terms “male” and “female” are sometimes applied to these connectors, the terms are not used in the standards themselves. Wikimedia Commons has media related to IEC 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”.

A similar but polarized connector has been made, but is not part of the standard. This coupler is sometimes colloquially called a cloverleaf coupler or ” Mickey Mouse ” because the cross section looks like the silhouette of the Disney character. Cables with a C13 connector at one end and a type E plug connector at the other are commonly available. 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.
For example, an E plug fits into an F outlet. 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 uec for international standardization and connecting computer equipment to the output of a uninterruptible power supply UPS.
Assembly and handling of an appliance is easier if the power cord can be removed without much effort. These data centre power cables are now offered in many colors which can be confusing to people unfamiliar with data centers.
Kettle plug is a colloquial term used for the high-temperature C16 appliance inlet and sometimes, wrongly, for the mating C15 connector. Xbox power supply  some vacuum cleaners, CPAP machines, audio equipment, televisions, medical devices. Many small switched-mode power supplies used for laptops. The C13 connector and C14 inlet are commonly found on computers, servers, routers, and switches.
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. Pin temperature is measured where the pin projects from the engagement surface. Selection of a coupler depends in part on the IEC appliance classes. The IBM Wheelwriter series of electronic typewriters are one common application.
Common on Enterprise-class servers, UPSs and datacenter rack-mounted power distribution units.
In addition the standards define further general criteria such as withdrawal forces, testing procedures, the minimum number of insertion cycles, and the number of flexings of cords.
