IEC Connectors
Description | Applications | Pin Assignments | Assembly Instructions
Mains input/output connector used on most equipment. 2-pin and 3-pin versions are available, as well as heat resistant versions for use on kettles etc. These have an extra cut-out below the earth pin to prevent mating with non heat resistant connector. Both chassis and line mounting plugs and sockets are available, so that they can be used for power input and output to equipment. Chassis plugs are also available with built-in fuses and switches. The plug MUST NOT be live when un-mated. Ideal for use on home-built projects; they are safer since straining the lead will pull the plug out rather than damaging the connections. The mains lead can also be easily swapped for use in different countries, but check before doing this that the equipment can operate on the voltage available.
Kitchen appliances - kettle, fryers etc (heat resistant version)
Computers, photocopiers, faxes etc. (normal 3 pin version)
Hi-Fi equipment (sometimes uses 2 pin version)
Other applications requiring mains input or output connectors
Viewing a socket (line or chassis) from the front, i.e. the side that the plug fits into, the connections are:
Left Pin: Neutral |

Connector Assembly Instructions:
Line Connectors:
Normally screw terminals. Ensure that the outer sheath of the flex is held under the cable clamp. If the connector has a strain relief sleeve, make sure you thread it onto the cable before you make the connections.
Chassis Connectors:
These are normally solder terminals or fast-on tabs, but are available with screw connections. Remember that if the connector bolts to the panel then the bolts should be earthed. (This is a convenient point to earth the panel, put a solder tag under one of the bolts.)
