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

Cord set: "assembly consisting of one cable or cord fitted with one non-rewirable plug and one non-rewirable connector, intended for the connection of an electrical appliance or equipment to the electrical supply". 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.

C13 Power Cables (Kettle Leads)

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. Plug connector: "part of the interconnection coupler integral with or intended to be attached to one cord". The C19 power cable is used in higher current applications such as power PDUs in data centres, it is an industrial type connector, larger than the C13 and C15. Schuko Euro Power Cables

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".Xbox One Power Supply | Xbox One Console". support.xbox.com.
