ABSTRACT:
According to the present invention there is provided an electrical appliance having a releasable cable connector for electrically connecting the appliance to a remote power supply, wherein a first junction means is adapted to provide the releasable electrical connection between the cable connector and the appliance, characterised by the provision of a second junction means adapted to provide a non-releasable, hard-wired electrical connection between an alternative cable connector and the appliance, wherein the first junction means and the second junction means are arranged and configured so that the selection and use of one of said junctions by attachment of one cable connector precludes the simultaneous selection of the other connector.
