ABSTRACT:
A wiring device is provided with three different ways in which the bared end of an electrical conductor can be coupled to the contacts inside the body of a wiring device. A clamping plate is placed upon the threaded body of a terminal screw. In a first arrangement the bared end is formed about the terminal screw and trapped between the head of the terminal screw and a first surface of the clamping plate which forces the conductor into firm contact with the first surface of the clamping plate. In another arrangement the straight bared end of the conductor is trapped between a second surface of the clamping plate and a contact plate. The movement of the conductor and clamping plate is controlled by the terminal screw. Apertures are placed in the bottom of the device housing adjacement the contacts in the housing. A contact arm, formed as a one-way clutch grips the straight bared end of a conductor to make contact with the contacts of the device but prevents withdrawal of the conductor.
