Impulse tests on cables and their accessories from SAI Global.
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. Appliance manufacturing may be simplified by mounting an jec coupler directly on the printed circuit board. Pin temperature is measured where the pin projects from the engagement surface.

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. Each appliance’s power system must be adapted to the different plugs used in different regions. Very common on personal computers and peripherals. Unlike IEC connectors, they are not coded for voltage; users must ensure that the voltage rating of the equipment is compatible with the mains supply.
Further sub-parts of IEC focus on special topics such as protection ratings and appliance specific requirements.
BS EN IEC – Impulse tests on cables and their accessories
A similar but polarized connector has been made, but is not part of the standard. The dimensions and tolerances for plug connectors and appliance outlets are given in standard sheets, which are dimensioned drawings showing the features required for safety and interchangeability.
The C1 coupler and C2 inlet were commonly used for mains-powered electric shavers. The power supply cord can be replaced easily if damaged, because it is a standardized part that can be unplugged and iecc.
From Wikipedia, the free encyclopedia. Type J outlets are used in a similar way. There is a similar polarized connector having one squared side, see outline belowbut this is not part of the standard.
Connectors are also classified according to the method of connecting the cord, either as rewirable connectors or non-rewirable connectors. Some desktop computers provide both a C14 inlet lower and a type F outlet upper for powering the monitor. The dimensions and tolerances for connectors and appliance inlets are given in standard sheets, which are dimensioned drawings showing the features required for safety and interchangeability.
Common on Enterprise-class servers, UPSs and datacenter rack-mounted power distribution units.
Most desktop computers use the C14 inlet to attach the power cord to the power supply, as do 60203 instrument amplifiersmonitors, printers and other peripherals. Commonly referred to as a Clover-leaf or Mickey Mouse connector due to its shape.

Retrieved 29 June Each type of coupler is identified by a standard sheet number. Three wire cords with C13 connectors, which are easier to ied, are sometimes used in place of the two wire cords for replacement. Many small switched-mode power supplies used for laptops. An appliance with a permanently-attached plug for use in one country cannot be readily sold in another which uses an incompatible wall socket; this requires keeping track of variations throughout the product’s life cycle from assembly and testing to shipping and repairs.
Very common for power distribution on computer and instrument equipment racks, used to be common as a means of connecting power from a PC to a monitor.
Standard sheet C25 shows retaining device dimensions. 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.
Typical applications with increased ied temperatures include appliances with heating coils such as ovens or electric grills. This is the Australian version of the IEC standard 660230 national variations shown. These are usually un-fused with the exception of C13 cords attached to BS plugs, which are always fused.
These have largely been supplanted by cordless shavers with rechargeable batteries or corded shavers which use an AC adapter. IEC cords are used to power many pieces of electronic equipment, including computers, instrument amplifiersprofessional audio equipment and virtually all professional video equipment.
A cord which is fitted with non-rewireable usually moulded connectors at both ends is termed a cord set.
