Patent number: 5241136Abstract: A wire cable attachment adapter unit is secured to the top or bottom ends of a circuit breaker or electric switch enclosure to provide strain relief to the electrical power distribution cables that connect with the circuit breakers or switches arranged within the enclosure. The cable support adapter includes a plurality of integrally-formed bulkheads projecting from a support base with upstanding side arms having serrated outer surfaces and separately formed U-shaped clamps having striations formed on the inner legs thereof. The U-shaped clamps are positioned over the side arms to form a cable-receiving channel. After electrical connections are made within the enclosure, the U-shaped clamps are forced against the side arms to fixedly trap the cables within the chamber.Type: GrantFiled: February 18, 1992Date of Patent: August 31, 1993Assignee: General Electric CompanyInventors: Gary P. Michaelis, Robert G. Markowski, John A. Morby

Patent number: 5241289Abstract: An industrial rated molded case circuit breaker fitted with an exhaust arc gas manifold arranged over ventilation slots of the circuit breaker and disposed at a line end thereof to redirect the arc exhaust gases exiting the ventilation slots. The exhaust arc gas manifold is fixedly attached to the circuit breaker to prevent an electric fault from occurring between the different phases of a multi-phase electric power distribution system connected to the line end of the circuit breaker. An electric fault is further prevented between the exiting arc gases and the line terminals attached to the circuit breaker thereof.Type: GrantFiled: July 24, 1992Date of Patent: August 31, 1993Assignee: General Electric CompanyInventors: Robert G. Markowski, James R. Pratt, Dean A. Robarge

The cable is arranged in an endless loop between the actuator handle and the circuit breaker operating handle. Moving the actuator handle in a first direction pulls the circuit breaker operating handle to its ON position while moving the actuator handle in an opposite direction pulls the circuit breaker operating handle to its OFF positoin. A retractable handle extender on the actuator handle increases the torquing force applied to the actuator handle and the circuit breaker operating handle.Type: GrantFiled: August 28, 1991Date of Patent: March 16, 1993Assignee: General Electric CompanyInventors: Robert G.

Patent number: 5172300Abstract: A combination panelboard-switchboard housing accepts plug-on connection with a plurality of modular electric switch-circuit breaker enclosures. The modular enclosure accepts circuit breakers or electric switches which can be field-installed with minor alteration to the enclosure. The modular switch enclosure further accepts a wide range of ampere ratings within a standard enclosure size. A mechanical latch arrangement on the bottom of the modular enclosure prevents the modular enclosure from being removed from the panelboard-switchboard housing. Controlled temperatures are achieved within the housing by optimized circulating air flow.Type: GrantFiled: March 16, 1992Date of Patent: December 15, 1992Assignee: General Electric CompanyInventors: John A. Morby, Robert J. Sabatella, Andre J. M'Sadoques, Robert G. Markowski, Christine T. Lamberti

Patent number: 5113312Abstract: A combination panelboard-switchboard housing accepts plug-on connection with a plurality of electric switch-circuit breaker modules. Circuit breakers can also be directly connected onto the bus bars in a plug-on connection with minor modification. The bus bars are "edge-mounted" such that the minor dimension of the bus bars is perpendicular to the bottom of the housing to receive the modules as well as the circuit breakers, per se. Electrical insulation shields are arranged over those bus bars that are not connected with the circuit breakers or modules to prevent inadvertent contact with the bus bars when energized. The tabs extending from the edge of the insulation shields are keyed to accommodate for the different widths of the modules when the insulation shields are flush-mounted against one side of the modules.Type: GrantFiled: March 22, 1991Date of Patent: May 12, 1992Assignee: General Electric CompanyInventors: James R. Pratt, Dean A. Robarge, Robert G. Markowski, Denis A. Perzan, John A. Morby

Patent number: 5067043Abstract: A combination panelboard-switchboard housing accepts plug-on connection with a plurality of electric switch-circuit breaker modules. Circuit breakers can also be directly connected into the bus bars in a plug-on connection with minor modification. The bus bars are "edge-mounted" such that the minor dimension of the bus bars is perpendicular to the bottom of the housing to receive the modules as well as the circuit breakers, per se. Plastic or fiber insulation shields are arranged over those bus bars that are not connected with the circuit breakers or modules to prevent inadvertent contact with the bus bars when energized.Type: GrantFiled: December 13, 1990Date of Patent: November 19, 1991Assignee: General Electric CompanyInventors: Robert G.

Patent number: 4959514Abstract: A Fusible electric switch is herein described for increased ratings within industrial electrical distribution circuits by the provision of an arc exhaust gas controller. The arc gas controller cools and deionizes the arc gases that are generated upon separation of the switch contacts and exhausts the gases in a predetermined direction outside the switch enclosure. Fuse pullers are arranged at one end of each of the switch fuses to facilitate both installation and removal of the fuses.Type: GrantFiled: September 11, 1989Date of Patent: September 25, 1990Assignee: General Electric CompanyInventors: Dean A.

Patent number: 4945450Abstract: A multi-component electric switch-circuit breaker module permits electric switches and circuit breakers to be field-installed within existing panelboard-switchboard enclosures. The module contains a pair of compartments that are accessed by separate doors. Electric switches or circuit breakers can be arranged within both compartments or an electric switch can be installed within one compartment with an electric circuit breaker installed within the other. The module is removably attached to the panelboard-switchboard interior by means of a bail handle arrangement. The module is removed from the assembly by unscrewing the bail handle and manually accessing the module. Spring-loaded connector clips allow for repeated connection with and disconnection from the systems power bus with minimum contact resistance.Type: GrantFiled: August 2, 1989Date of Patent: July 31, 1990Assignee: General Electric CompanyInventors: Robert J.

Patent number: 4902864Abstract: A fast operating disconnect switch minimizes the arc that occurs when the switch contacts are opened or closed by operation of a rotor assembly while the switch is electrically energized. A powerful operating spring within the operating mechanism under the control of a handle operator assembly overcenters upon the ON-OFF as well as OFF-ON movement of the handle operator. The handle operator assembly is adapted for either left-hand or right-hand mounting to a common rotor assembly.Type: GrantFiled: December 9, 1988Date of Patent: February 20, 1990Assignee: General Electric CompanyInventors: Robert G.
