Abstract: An enclosed switching apparatus includes an enclosure and a primary power supply disconnect mounted in the enclosure. The primary power supply disconnect has first and second terminals, the first terminals are electrically connectable to a primary power source and the second terminals are electrically connectable to a load. An auxiliary power supply unit includes an auxiliary power supply disconnect having third and fourth terminals. The third terminals are electrically connectable to the primary power source. A transformer has fifth and sixth terminals, the fifth terminals are electrically connected to the fourth terminals of the auxiliary power supply disconnect. An auxiliary fusible element has seventh and eighth terminals, the seventh terminal is electrically connected to one of the sixth terminals of the transformer. A receptacle has ninth terminals thereon. One of the ninth terminals is electrically connected to the eighth terminal of the auxiliary fusible element.

Abstract: A locking assembly is for a circuit breaker including an enclosure and an operating handle operable between a first, ON position and a second, OFF position with respect to the enclosure. The operating handle includes a first aperture extending therethrough. The locking assembly includes a stationary element coupled to the enclosure and includes a second aperture extending therethrough. The second aperture corresponds with the first aperture of the operating handle when aligned therewith. A blocking element coupled to the operating handle blocks the second aperture when the operating handle is disposed in any position other than the second, OFF position in which the first aperture extending through the operating handle is aligned with the second aperture of the stationary element. A lock is inserted through the aligned apertures in order to lock the operating handle in the second, OFF position.

Abstract: A single piece fuse clip and switch blade contact receptacle is provided for use with an electrical switch, which may be a safety switch. The present invention provides an apparatus which eliminates the need for multiple connections, and which consolidates a switch blade receptacle portion with a fuse clip section in a single piece device employed in an electrical switching environment.

Abstract: A pair of slides (20,22) linearly reciprocally movable in opposite directions by a single operator handle (36) carry pins (24,26) which are received within dog-leg slots (14a,14b; 14a',14b') of levers (14,14') affixed to rotary operating mechanisms (6,6') of repsective ones of a pair of switches (4,4') for operating one switch to an ON condition while maintaining the other switch in its OFF condition in response to handle (36) movement in one direction, and for operating the switches to their reverse conditions in response to handle movement in an opposite direction, both switches being in their OFF condition in a center neutral position of the handle. Fuses (40,42) are connected to load side terminals of the switches and are connected together in common with the load to remove power from the fuses when the switches are OFF.
