IEC 60320

IEC 60320 is a set of standards from the International Electrotechnical Commission specifying non-locking electrical power couplers for the connection of power supply cords to electrical appliance up to 250 V. Couplers described under these standards have standardized current and temperature ratings. Use of standard inlets and country-specific cord sets allows manufacturers to produce the same appliance for many markets, where only the cord set has to be changed for a particular market. Compatible connectors are also made for equipment that requires power outlets for interconnection.

Different types of connector (distinguished by shape and size) are specified for different combinations of current, temperature and earthing requirements. Unlike IEC 60309 connectors, they are not coded for voltage; users must ensure that the voltage rating of the equipment is compatible with the main supply.

Each type is identified by a standard sheet number, consisting of the letter C followed by a number, where the standard sheet for the inlet is 1 higher than the sheet for the corresponding cable connector. As well as the codes given in the specification many types have common names. The most common names are IEC connector for the common C13/C14, the figure eight connector for C7/C8, and the cloverleaf connector or Mickey Mouse connector for the C5/C6. A kettle plug may refer to either the high-temperature C15/C16 or the regular temperature C13/C14 connectors.

The first edition of IEC 320 (later renumbered IEC 60320) was published in 1970.
