3M IEC C7 Figure of 8 Eight Mains Power Cable Lead - 3 Metre Long (Black)

Product Information

The C7 socket is often commonly known as a cassette or calculator style socket, and can be used in a wide range of small or portable appliances. 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). Power cable assemblies are defined as any power cable which has had a connector installed prior to sale.

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. 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. In addition to the connections within the standards, as mentioned, there are possible combinations between appliance couplers and IEC interconnection couplers. Everything looks cool - I'll spend the day tomorrow re-arranging the studio and installing the new leads.

For appliance couplers this consists of the letter "C" followed by a number, where the standard sheet for the appliance inlet is 1 higher than the sheet for the corresponding cable connector.

Further sub-parts of IEC 60320 focus on special topics such as protection ratings and appliance specific requirements.Kettle/jug plug” is also informally used to refer to regular temperature-rated C13 and C14 connectors. The general requirements for these items were incorporated into IEC 60320-1 and the standard sheets were moved to IEC 60320-3.

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). 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. For appliance couplers the various coupler outlines are designated using a combination of letters and numbers, e. These are similar in form to the C13/C14 coupler, except with a ridge opposite the earth in the C16 inlet (preventing a C13 fitting), and a corresponding valley in the C15 connector (which doesn't prevent it fitting a C14 inlet).I think you should have a section on your web site saying that you can make leads for early Quad stuff. 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.
