Abstract: An in-line cord ground fault circuit interrupter which contains within a common housing the sensing unit and the tripping relay usually found separately packaged at a remote location. The fixed contacts are mounted on fixed contact arms mounted adjacent one surface of a printed circuit board with the movable contacts mounted on movable contact arms mounted adjacent the second surface. The tripping relay operates an armature between an open and a closed condition and by cams on the arms of the armature opens and closes the movable contacts with the fixed contacts. The two portion housing allows the components of the interrupter to be mounted on one portion of the housing which also supports the line and load conductors making assembly of the rear housing portion to the front housing portion easy. A stop member and a positioning post are provided on the interior of the front cover to check the position of the armature in the non-energized state to verify proper contact placement and gaps.

Abstract: In a ground fault circuit interrupter (GFCI), a pair of flexure arms having moveable contacts disposed thereon are deflected in response to the activation of a solenoid having a moveable core. The core of the solenoid causes a pair of cam actuators which are preferably coupled together by a catcher to rotate. The rotation of the cam actuators causes the deflection of the flexure arms, thereby separating the moveable contacts from the stationary contacts and interrupting the flow of current. The activation of the solenoid is controlled by an electronic module. The electronic module includes a detection circuit which inhibits the solenoid from opening the contacts until there is sufficient electrical energy to insure that the kinetic energy of the solenoid will cause the contacts to latch open. The electromechanical current interrupter and the electronic module are disposed within a housing that can be mounted within a standard electrical receptacle box.

Abstract: A threaded fastener quick-fastening clip member is adapted to be slidably lockably engaged in a slotted channel adjacent a lug which is formed with an unthreaded borehole communicating the front face of the structure with the channel. A first leg portion of the clip member is inserted in slot means formed in the channel and is provided with generally rigid but resilient detent means for lockable engagement therein. A second leg portion, intersecting the first leg at an obtuse angle, extends into the channel and is formed with an aperture for registering with the borehole and engaging a threaded fastener. A canopy may cover a portion of the slotted channel adjacent the lug for providing stop means to prevent over-excursion of the second leg portion of the clip member.

Abstract: Knockout window means include a knockout port formed primarily in a sidewall of an electrical assembly box and a knock-out panel superposed over the knockout port from the inside of the sidewall. The knockout panel is attached only at its front and back ends to the box, the front end being connected to the inside surface of the sidewall and the back end being connected to the backwall, each by a frangible web which provides doubly accessible panel removal slot means between each end of the knock-out panel and the structure to which each is attached. The panel removal slot means are accessible from both the outside and the inside of the assembly box at each end of the knockout panel, and include four pairs of bearing surfaces against which a wedge-like tool may bear for applying twisting leverage to fracture the webs.
