A C8B inlet type is defined by the 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. [22] Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors. 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.
Some electric kettles and similar hot household appliances like home stills use a supply cord with a C15 connector and a matching C16 inlet on the appliance; their temperature rating is 120°C (248°F) rather than the 70°C (158°F) of the similar C13/C14 combination. The official designation in Europe for the C15/C16 coupler is a "hot-condition" coupler. 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. 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).
The C17/C18 coupler is often used in audio applications where a floating ground is maintained to eliminate hum caused by ground loops. Other common applications are the power supplies of Xbox 360 game consoles, replacing the C15/C16 coupler employed initially, and large CRT televisions manufactured by RCA in the early 1990s. In European countries the C15/C16 coupler has replaced and made obsolete the formerly common types of national appliance coupler in many applications. These cables are sometimes informally referred to as a "kettle cord" or "kettle lead", but the C13/14 connectors are only rated for 70°C (158°F): a device such as a kettle requires the C15/16 connector, rated for 120°C (248°F). For use in high-temperature settings (for example, electric kettle). Also used in some network appliances that provide PoE. This is exploited by high-powered computer power supplies, up to 1200W output, and even some particularly efficient 1500W output models [16] to use the more popular C14 input on products sold worldwide.
Appliance outlet: "part of the interconnection coupler which is the part integrated or incorporated in the appliance or equipment or intended to be fixed to it and from which the supply is obtained". Interconnection couplers are similar to appliance couplers, but with the gender roles reversed. Specifically, the female appliance outlet is built into a piece of equipment, while the male plug connector is attached to a cord. They are identified by letters, not numbers, with one letter identifying the plug connector, and the alphabetical next letter identifying the mating appliance outlet. For example, an E plug fits into an F outlet. Beginning with an amendment published in 2022, three of the commonly used high temperature variants have been standardized as types M–R. [26] C13/C14- This connector is used for larger electrical appliances, such as kitchen appliances, instrumentation amplifiers and computer hard drives. 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.Xbox One Power Supply | Xbox One Console". support.xbox.com. Archived from the original on 2016-11-26 . Retrieved 2016-11-25. The mains appliance couplers are all engineered to connect an appliance via a power cord to mains power.
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. 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.C5/C6- Known as a cloverleaf, this power connector is used in smaller electrical appliances such as projectors. Australian/New Zealand Standard AS/NZS 60320.1:2004, Appliance couplers for household and similar general purposes Part 1: General Requirements (IEC 60320-1, Ed. 2.0 (2001) MOD). This is the Australian version of the IEC standard with national variations shown. This kind of coupler is used by Roland Corporation for a couple of synthesizer and drum-computer models (for example: TR-909, D-50) and by Revox for many older models of their hi-fi equipment (for example, A76, A77, A78, B77, B225). Was also used heavily on Marantz hi-fi equipment in the 1980s and 1990s. 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. IEC 60309 specifies larger couplers used for higher currents, higher voltages, and polyphase systems.
Appliances can be used in another country easily, with a simple change of the power supply cord (including a connector and a country-specific plug). The power supply cord can be replaced easily if damaged, because it is a standardized part that can be unplugged and re-inserted. Safety hazards, maintenance expenditure and repairs are minimized. The C13 connector and C14 inlet are also commonly found on servers, routers, and switches. Power cord sets utilizing a C13 connector and an E interconnection plug are commonplace in data centers to provide power from a PDU (power distribution unit) to a server. These data-center power cables are now offered in many colors. Colored power cables are used to color-code installations. [25] C15/C16 coupler [ edit ]
Similar connector to C5/C6, but with a key ridge instead of an earthing conductor, withdrawn from standard. Similar to C13/C14 coupler, but unearthed. A C18 inlet accepts a C13 connector, but a C14 inlet does not accept a C17 connector. C7/C8- The figure-eight connector is commonly used in personal stereo systems and some older laptop models.
