  • Patent number: 9434268
    Abstract: An electric vehicle recharging station that can be readily incorporated into existing building electrical distribution systems during retrofit or new construction. The system has at least one enclosure and a vehicle charging connector. A circuit interrupter has line terminals for connection to respective first and second phases of the distribution system. A contactor relay has first and second phases coupled to the respective circuit interrupter and electric vehicle charging connector phases and separable contacts for each phase, for selective connection of electric power to the charging connector. A recharger controller is coupled to the contactor, for causing selective separation and closing of the separable contacts, so that electrical power is transferred to the electric vehicle. The recharging station system may also incorporate electric rate metering functions as well as communication capability from the controller to a remote controller. A human machine interface may be coupled to the controller.

  • Patent number: 8369052
    Abstract: The present invention relates generally to a circuit breaker. More particularly, the invention encompasses a modular circuit breaker. The present invention is also directed to a novel a modular circuit breaker with a trip bar. The inventive two pole residential circuit breaker includes an Arc Fault and Ground Fault electronic detection system. The modular breaker design includes an electronic system used for tripping a designated mechanism pole which in turn trips the secondary mechanism pole. Electronic components are included that sense the continuous current flow through each mechanism pole simultaneously to determine when a trip event is needed. The electronic system of this invention includes a self diagnostic system with electronic visual indicators that display the method of which trip condition occurred.

  • Patent number: 8267562
    Abstract: An apparatus, method and system for visually indicating a circuit breaker, such as a multi-pole circuit breaker, has been tripped are provided. An exemplary light guide comprises a plurality of light conduits adapted to transmit light from two or more light sources within a circuit breaker assembly to an exterior of the circuit breaker assembly; a beam that connects the light conduits; and one or more retention features coupled to one or more of the light conduits, wherein each retention feature is adapted to mate with a retention feature interface of the circuit breaker assembly. Numerous other aspects are provided.

  • Patent number: 8241074
    Abstract: Embodiments provide circuit breakers with stops adapted to prevent a lug screw from falling out of circuit breaker and/or to prevent the lug screw from blocking a wire receiver of circuit breaker lug body. In one aspect, a circuit breaker is provided having a circuit breaker housing; a lug assembly retained in the circuit breaker housing, the lug assembly including a threaded screw hole; a lug screw having driving end and a threaded shaft inserted in the threaded screw hole; and a back-out stop adapted to contact the driving end and limit an extent of backward movement of the lug screw out of the threaded screw hole. Other aspects are provided.

  • Patent number: 8134428
    Abstract: A circuit breaker and method includes a mechanical pole moveable between a latched position and an unlatched position to open an electrical connection between a pair of electrical contacts. An electronic tripping device is configured to respond to a sensor signal. The sensor signal is output from a condition sensor wherein upon receiving the sensor signal the electronic tripping device trips the mechanical pole into the unlatched position.

  • Patent number: 8049122
    Abstract: A circuit breaker includes a housing forming an opening. A push switch is connected to a test circuit to enable testing of the test circuit in accordance with closing the push switch. A flexible membrane is formed in the opening and configured to form a seal between the housing and the flexible membrane. The flexible membrane is located in an operative relationship with the push switch such that pushing the flexible membrane results in a displacement of the push switch.

  • Patent number: 7986203
    Abstract: A multi-pole circuit breaker and method include at least two breaker modules including circuit breakers therein. The circuit breakers include a moveable arm configured to connect and disconnect contacts therein. The at least two modules including armatures connectable to the moveable arms of each of the at least two modules. A center module connects the at least two modules. The center module includes an actuator and a beam connected to the actuator at a mid-portion. The beam connects to each armature of the at least two modules wherein under a trip condition the actuator displaces the beam to simultaneously trip the at least two modules using the armatures.

  • Patent number: 7804314
    Abstract: An electrical probe assembly includes a first probe housing pivotally connected to a base structure and receiving a first probe therein. The first probe is configured to interface with a first contact of an electrical component. A second probe housing is pivotally connected to the base structure and receives a second probe therein. The second probe is configured to interface with a second contact of the electrical component wherein the first and second contacts have a spatial relationship therebetween. An adjustment mechanism is connected to the first and second housing and configured to independently adjust an amount of rotation of the each of the housings to accommodate the spatial relationship.
