LINDY 30444 2 m UK 3 Pin Plug To IEC C7 Mains Power Cable - Black

Product Information

We often find that people are unsure of the difference between mains power cables, or what the IEC standards are. To put it simply, the standards define the mechanical, electrical and thermal requirements and safety requirements of power couplers. 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 IBM Wheelwriter series of electronic typewriters are one common application. Three-wire cords with C13 connectors, which are easier to find, are sometimes used in place of the two-wire cords for replacement. In this case, the ground wire will not be connected. For everything to domestic kitchen equipment to computer hardware in office environments, the IEC connector is available in different sizes and shapes to accommodate the current, temperature and earthing requirements of different appliances.

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:

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.

IEC 60320-2-2: Interconnection couplers for household and similar equipment. This section was withdrawn in January 2016. The general requirements for these items were incorporated into IEC 60320-1 and the standard sheets were moved to IEC 60320-3. The mains appliance couplers are all engineered to connect an appliance via a power cord to mains power. In addition to the connections within the standards, as mentioned, there are possible combinations between appliance couplers and IEC interconnection couplers. Fitted with a flexible cord, the components become interconnection cords to be used for connecting appliances or for extending other interconnection cords or power supply cords. For use in high-temperature settings (for example, electric kettle). Also used in some network appliances that provide PoE. 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."

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. 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).

Interconnection cord set: "assembly consisting of one cable or cord fitted with one non-rewirable plug connector and one non-rewirable connector, intended for the interconnection between two electrical appliances".

In addition the standards define further general criteria such as withdrawal forces, testing procedures, the minimum number of insertion cycles, and the number of flexings of cords. 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. 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. 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.

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). IEC Connectors are used as power couplers for electrical appliances. IEC refers to the set of standards from the International Electrotechnical Commission, ensuring that the power cords for appliances conform to a standardized set of safety requirements for appliances not exceeding a 250 V ac voltage or 16 A rated current. International Standardized Appliance Connectors (IEC-60320) Reference Chart Includes diagrams of all couplers, their rated current, equipment class, and temperature rating.C13/C14- This connector is used for larger electrical appliances, such as kitchen appliances, instrumentation amplifiers and computer hard drives. Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors.
