Abstract
An apparatus for use in arcing fault detection systems within circuit breakers and which is adapted for automated production by top-down assembly. The invention also includes several devices for making electrical connections to the circuit breakers, including a lug having a top and a hollow center, the top having a hole connecting the top to the hollow center for accessing a wirebinding screw, a neutral bus having a first end and a second end, the first end disposed within the hollow center beneath the hole, a wire binding screw disposed in the hole and extending through the hollow center for securing a first wire to the first end of the neutral bus, and a strain relief member connected to the second end of the neutral bus for securing a second wire connected to the second end of the neutral bus. In another embodiment, a strain relief member has a top section and a bottom section, the top section being substantially flat and having a threaded hole disposed therein and adapted for use in securing a wire by means of a screw engaging said threaded hole, the bottom section defining a cavity for receiving a wire, the top section and the bottom section being connected together and separa…
