A similar but polarized connector has been made, but is not part of the standard. Sometimes called C7P, it is asymmetrical, with one side squared. 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. Although not specified by IEC 60320, and not clear whether any formal written standard exists, the most common wiring appears to connect the squared side to the neutral, and the rounded to the hot line. [23] [24] Note: Clause 9.5 was added to IEC 60320-1:2015, this requires that "It shall not be possible to engage a part of a non-standard appliance coupler with a complementary part of an appliance coupler complying with the standard sheets in any part of IEC 60320." 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). 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 of the most recognizable songs of all time, “When the Saints Go Marching In” straddles the lines between gospel, pop, and jazz. Instantly evoking the feel of New Orleans, you don’t need a full horn section to see how the C7 chord gives this classic its punch. Incorporating bass note strumming - along with the chords themselves - makes this song a little more challenging and even more fun to try to play. Blues Songs

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. Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors. Non-rewirable plugs and connectors are typically permanently molded onto cords, and cannot be removed or rewired without cutting the cords. Earthed, 16A, polarized. This coupler is used for supplying power in IT applications where higher currents are required, for instance on high-power workstations and servers, power to uninterruptible power supplies, power to some power distribution units, large network routers, switches, blade enclosures, and similar equipment. This connector can also be found on high-current medical equipment. It is rectangular and has pins parallel to the long axis of the coupler face. IEC 60320-2-1: Sewing machine couplers [6] specifies couplers which are not interchangeable with other couplers from IEC 60320, for use with household sewing machines. They are rated no higher than 2.5A and 250V AC.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. Similar to C13/C14 coupler, but unearthed. A C18 inlet accepts a C13 connector, but a C14 inlet does not accept a C17 connector. The dimensions and tolerances for connectors, appliance inlets, appliance outlets and plug connectors are given in standard sheets, which are dimensioned drawings showing the features required for safety and interchangeability. 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". 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.

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). Commonly known as a "figure-8", "infinity" or "shotgun" connector due to the shape of its cross-section, or less commonly, a Telefunken connector [21] after its originator. International Standardized Appliance Connectors (IEC-60320) Reference Chart Includes diagrams of all couplers, their rated current, equipment class, and temperature rating.

Very common on personal computers and peripherals. Commonly referred to as a "kettle cord" or "kettle lead", [17] [18] but kettles in countries using 120V require the C15/C16.
