ABSTRACT:
An electrical coupling for use in an appliance such as a kettle or hot water jug comprises an inlet in the appliance having a standard pin configuration, but a non-standard profile to prevent a standard connector being inserted therein. A connector for engagement therewith has a standard socket configuration but a non-standard shape to prevent it being inserted in a standard inlet. The polarity of the line and neutral terminals within the connector is reversed with respect to the standard configuration.
