    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include an independent trip mechanism and a reset lockout mechanism are provided. The trip mechanism operates independently of a circuit interrupting mechanism used to break the connection, and the reset lockout mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism is non-operational or if an open neutral condition exists.

    Abstract: An arc fault detector system detects arcing faults in an electrical distribution system by monitoring one or more conductors and producing an input signal representing one or more electrical signal conditions in the circuit to be monitored. This input signal is processed to develop signals representing the electrical current flow through the monitored circuit and broadband noise signal components. The system analyzes these signals to determine whether an arcing fault is present, and if so, outputs a trip signal which may be used directly or indirectly to trip a circuit breaker or other circuit interruption device.

    Abstract: An arc fault circuit breaker (10) conducting an electric current to a protected load is presented. The circuit breaker (10) has a first (mechanical) compartment (24) and a second (electrical) compartment (62). A bimetal resistor (50) is disposed within the first compartment (24) and conducts the current therethrough. The bimetal resistor (50) has a stud (56) extending into the second compartment (62). A single sense line (60) is electrically connected to the bimetal resistor (50) and routed into the second compartment (62). The sense line (60) and said stud (56) conduct a voltage signal indicative of arcing of the current. A circuit board (84) is disposed within the second compartment (62) and is connected to the sense line (60) and stud (56) within the second compartment (62) to process the voltage signal. The circuit board (84) has a first conductive path (104) electrically connected to the stud (56), and a second conductive path (106) electrically connected to the sense line (60). The first and second conductive paths (104,106) run substantially parallel and proximate to each other such that electromagnetic interference of the voltage signal is substantially reduced.

    Abstract: A circuit breaker for interrupting electrical current flowing through a line conductor to a load terminal in response to the detection of a current overload, ground fault and/or arcing fault. The circuit breaker has a trip circuit to generate a trip signal, a releasably latchable trip lever, and a latching mechanism. The trip lever is moveable between a latched position and a tripped position. In the latched position, the trip lever engages the latching mechanism and the electrical current flows through said circuit breaker. When a fault is detected by the trip circuit, a trip signal is send to the latching mechanism. Upon receiving the trip signal, the latching mechanism disengages the trip lever allowing the trip lever to slide into the tripped position and interrupting the current flow through the circuit breaker.

    Abstract: Apparatus for generating alarms for a group of circuit interrupters, especially those which respond to arcing faults, includes a device associated with each circuit interrupter providing an indication of a tripped condition and a common alarm generator which generates an alarm when any one, or at least any one of a number of selected circuit interrupters, is in the tripped condition. In one embodiment of the invention, switches indicating that associated circuit interrupters are tripped generate auxiliary trip signals on a common alarm bus. The auxiliary trip signals are latched by a latch on the common alarm bus which energizes a relay to activate a local and/or remote alarm. The latch is reset by a switch on the load center door. In another embodiment of the invention, an IR beam is blocked from reaching a photo-detector whenever a circuit interrupter handle is in the tripped position which also results in energization of a relay to actuate the common alarm. Selected circuit interrupters only can be alarmed by orienting the light beam such that only circuit interrupters selected by adding an extension to the handle block the beam when the associated circuit interrupter is tripped.
