Abstract: Systems, methods, devices, and computer-readable media secure a coupler 101 of an electric vehicle charging station 100 by locking the coupler 101 to the electric vehicle charging station 100 or an electric vehicle 210. A locking mechanism is provided within the coupler 101. The locking mechanism may include an actuator 432 configured to move between a lock and unlock position. When the actuator 432 is in the lock position, the coupler 101 may be locked to the charging station 100 or an electric vehicle 210. Whereas, when the actuator 432 is in the unlock position, the coupler 101 may be removed from the charging station 100 or electric vehicle 210. Further, the charging station 100 may include an identification device 437 for determining when to lock or unlock the coupler 101.

Abstract: A self-powered, self-contained, signage device includes a bistable display with its state-change power received from an actuator handle or pushbutton attached to a mechanically activated generator integral to the display. The device may be integrated into actuating members for various equipment types thereby providing a highly visible status indication of equipment operations.

Abstract: A load center includes a housing, a cover, and a circuit breaker. The load center can be retrofitted to further include a rotational motor, an actuator member, and a guide insert. The rotational motor includes a threaded drive shaft positioned through an aperture formed in the cover. The actuator member is threadingly engaged with the threaded drive shaft. The actuator member is oriented relative to the cover such that a handle of the circuit breaker is positioned through an aperture of the actuating member. Rotation of the threaded drive shaft causes the actuator member to translate such that a first actuating surface of the actuator member engages the handle and switches the handle from an OFF position to an ON position. The handle of the circuit breaker has full range of travel between the ON and OFF positions in response to the actuator member being moved into a neutral position.

Abstract: A highly accurate current sensing transformer, such as an external neutral current transformer (ENCT), accommodates a wide range of loads. The ENCT includes a housing, first and second terminals each having an end portion extending from and external to the housing, a conductor for carrying a current to be measured, and a current sensor having an aperture for receiving the conductor and having a central axis. The conductor joins the first and second terminals to form a current path that passes through the aperture. Increased accuracy is achieved by arranging the conductor such that a portion thereof passing through the aperture forms a substantial angle relative to the central axis, such that the entry angle of the current path via the conductor through the aperture of the current sensor of the ENCT matches an entry angle of a conductor through an aperture of a current sensor in the electronic trip unit to which the ENCT is attached.
