Power Cable UK (Type G) to IEC 320 C13 10A 1.5m / 2.5m Cable for Computer PSU misc. Appliances

This 13 amp plug has three rectangular prongs that form an isosceles triangle. The central earth pin is 4 by 8 mm and 22.7 mm long. Line and neutral pins are 4 by 6.35 mm and 17.7 mm long, on centres spaced 22.2 mm apart. The centre-to-centre distance between the earth pin and the middle of the imaginary line connecting the two power pins is 22.2 mm. The 9-mm long insulated sleeves prevent accidental contact with a bare connector while the plug is partially inserted.

British Standard BS 1363 requires use of a three-wire grounded and fused plug for all connections to the power mains. Two-wire class II appliances are not earthed and often have a plastic grounding pin which only serves to open the shutters of the outlet. The lack of such an earth pin on a type C plug makes it impossible to connect it to a type G receptacle, although it can actually be forced into the socket by sticking a pointy object into the centre hole of the power outlet, which opens up the two other holes.

Most desktop computers use the C14 inlet to attach the power cord to the power supply, as do many instrument amplifiers, monitors, printers and other peripherals. 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. IEC cords are used to power many pieces of electronic equipment, including computers, instrument amplifiers, professional audio equipment and virtually all professional video equipment.

There are also a variety of splitter blocks, splitter cables, and similar devices available. These are usually un-fused (with the exception of C13 cords attached to BS 1363 plugs, which are always fused).

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).

A cable consisting of a C13 and C14 connector is commonly mislabeled as an "extension cord", as although that is not the intended purpose, it can be used as such.
