North American rating agencies ( CSA, NOM-ANCE, and UL) will certify IEC 60320 connectors for higher currents than are specified in the IEC standard itself. In particular, UL will certify: CIE is one of the UK's leading and most innovative professional AV distributors and are widely accepted as the experts in commercial sound systems design and supply. 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. The C13/C14 connector and inlet combination are used in a wide variety of electronic equipment ranging from computer components like the power supply, monitors, printers and other peripherals to video game consoles, instrument amplifiers, professional audio equipment and virtually all professional video equipment. 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. Earthed – High temperature version of the IEC C13 – Used extensively in recent HP servers and Cisco kit
The C1 coupler and C2 inlet were commonly used for mains-powered electric shavers. These have largely been supplanted by cordless shavers with rechargeable batteries or corded shavers with an AC adapter. Plug connector: "part of the interconnection coupler integral with or intended to be attached to one cord".

On a standard power cord, the power is drawn from the mains and the electricity will run through the wire and arrive at its destination. This can be either into a power supply or directly into the appliance/machine itself. Due to the range of voltages available, different types of cable assemblies will suit varying requirements. What type of cable material is available? Xbox One [19] and some Xbox 360 power supplies, [20] some vacuum cleaners, CPAP machines, audio equipment, televisions, medical devices, IBM Wheelwriter typewriters. 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.
Power cords are defined as any power cable which has had a connector installed prior to sale. There are versions that may have one connector and an unterminated end. Some assemblies may have a connector a plug. And some assemblies will even have 2 connectors (IEC lead extension). Depending on the application, there are various types to suit the needs. What are these cable assemblies used for? IEC 60320-1 defines a cord set as an "assembly consisting of one cable or cord fitted with one plug and one connector, intended for the connection of an electrical appliance or equipment to the electrical supply". 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". 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. UL certification E152635 covering YC-12 C13, YC-20 C15 and YP-32 C14 connectors. Note that the manufacturer's YC-20 label contains an error; the wire gauges (18, 16, 14) are repeated in the "current rating" column; the UL certification contains the correct values (10A, 13A, 15A).

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. 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. 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. Power cords are used in almost every device or machine which requires electricity. From toasters and kettles, all the way up to generators and giant industrial equipment. Cable assemblies may vary in length, but the electrical current will perform at the same high capacity regardless of the distance it will need to travel. IEC 60320-1: General Requirements [1] specifies two- pole and two-pole with earth couplers intended for the connection of a mains supply cord to electrical appliances. Beginning with the IEC 60320-1:2015 edition, [5] this part also specifies interconnection couplers which enable the connection and disconnection of an appliance to a cord leading to another appliance, incorporating IEC 60320-2-2. At the same time, this part of the standard no longer includes standard sheets which were moved to a new part: IEC 60320-3.
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). 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]Non-rewirable plugs and connectors are typically permanently molded onto cords, and cannot be removed or rewired without cutting the cords. Pin temperature is measured where the pin projects from the engagement surface. The maximum permitted pin temperatures, are 70°C (158°F), 120°C (248°F), and 155°C (311°F), respectively (the higher temperatures are not applicable to interconnection couplers). The pin temperature is determined by the design of the appliance, and its interior temperature, rather than by its ambient temperature. Typical applications with increased pin temperatures include appliances with heating coils such as ovens or electric grills. It is generally possible to use a connector with a higher rated temperature with a lower rated appliance inlet, but the keying feature of the inlet prevents use of a connector with a lower temperature rating.
One of the most common plugs found on mainland Europe is the Schuko connector, used in France Germany and many other European countries. US Power Cables The C7 figure 8 power lead is a 2 pin power cable, when viewed end on it looks like a number 8. Often found on small electrical appliances like radios and CD players.

Standard sheet C25 shows retaining device dimensions. Sheet C26 shows detail dimensions for pillar-type terminals, where the end of the screw bears on a wire directly or through a pressure plate. Sheet 27 shows details for screw terminals, where the wire is held by wrapping it around the head of a screw. The first edition of IEC 320 was published in 1970 [2] and was renumbered to 60320 in 1994. [3] Terminology [ edit ]
