    摘要： A circuit breaker (such as a miniature circuit breaker) that wirelessly communicates state and fault information to a main energy monitoring module. The wireless circuit breaker includes a transceiver and a power supply that harvests energy inductively from the line current conductor without the need for a connection to a neutral conductor. The wireless circuit breaker can be implemented in the same package as existing circuit breakers, eliminating the need to replace the panel when upgrading to a system that employs a main energy monitoring module. The wireless circuit breaker can also include an energy storage device for supplying power to the circuit breaker after it has tripped, allowing the circuit breaker to transmit information after a trip. The main energy monitoring module includes a processor and a gateway for evaluating and transmitting information received from the circuit breaker to other applications, such as webpages and smartphones.

    摘要： A multi-pole circuit breaker comprising a single main housing containing multiple circuit breakers for protecting multiple branch circuits. Each of the circuit breakers comprises a single line terminal for receiving electrical current from a utility line, a plurality of load terminals for supplying electrical current from the single line terminal to a plurality of branch circuits via load lines, and a plurality of neutral terminals for receiving electrical current returned from the branch circuits via neutral lines Line conductors inside the main housing connect the line terminal to the plurality of load terminals. Sensors inside the main housing generate signals representing characteristics of the electrical current flow in the branch circuits, and a signal processor uses the signals generated by the sensors for detecting abnormal conditions in the branch circuits and generating trip signals in response to the detection of an abnormal condition. A single tripping mechanism between the line terminal and the load terminals receives the trip signals and interrupts the flow of current to the branch circuits in response to a trip signal.

    摘要： A circuit breaker includes for each neutral and phase power conductor, a current sensor sensing an alternating current flowing in a corresponding power conductor, a comparator determining whether the sensed alternating current is positive or negative, a rectifier rectifying the sensed alternating current to provide a rectified current value, and an analog-to-digital converter converting the rectified current value to a signed digital value having a positive sign. A processor cooperates with the comparators and the analog-to-digital converters and includes a routine that changes the positive sign of the signed digital value to a negative sign if the sensed alternating current is negative, adds the signed digital value for each power conductor to provide a sum, and employs the sum to determine whether to output a ground fault signal. The processor further cooperates with an operating mechanism to trip open separable contacts responsive to the ground fault signal.

    摘要： A ground fault circuit interrupter (GFCI) for opening a circuit when a ground fault has been detected in an attached circuit includes a current path structure containing no more than one splice and no more than one pair of contacts. A cantilevered movable contact arm and an activation device that moves in a linear fashion can be provided to open the current path structure when a ground fault is detected by the GFCI. In addition, the GFCI can include a transformer boat and solenoid bobbin that are snap fit onto a circuit board and located adjacent each other to provide rigidity to the circuit board and GFCI. The GFCI can be tested by a test switch that includes an integral cantilevered extension from an electrical terminal disposed over a resistor such that the cantilevered extension can be bent by a test button to contact a lead of the resistor and simulate a ground fault condition for the GFCI. Furthermore, the GFCI can include a housing with an outer portion that defines a uniform width channel adjacent a wire contact point to allow quick and easy connection to ground wires.
