    摘要: A low cost communications device such as a modem reduces electrical interference or noise of signals received from a power line and transmitted to electrical devices. The modem forwards messages and commands between electrical devices and an external computer device. That is, the modem communicates over a power line without the use of a controller such as a microprocessor or microcomputer. The modem can reduce electrical interference of signals received from a power line through the use of an adjustable automatic gain (AGC) circuit.

    摘要: A resettable switching apparatus, useful in a GFCI receptacle, has a space-efficient coaxial configuration in which a mechanical latching arrangement for resetting (i.e., closing) main switch contacts is disposed inside the trip solenoid. A movable carriage for the main contacts spans one end of the solenoid and has a latching portion in the solenoid that engages the inner end of a reset plunger in two sequential states (i.e., unlatched and latched). An electrical miswire feature is included to prevent the device from being reset until the AC power is properly connected to the device and inadvertent failure of the miswire feature due, for example, to dropping the device prior to installation is avoided. Also, an enhanced self-test, or auto-monitoring, feature is provided that is more robust than that which has been previously disclosed.

    摘要: A ground detector circuit in the form of a live ground detector circuit. This live ground detector circuit can be combined with a circuit interrupting device. The circuit interrupting device can have a grounding conductive path, and a set of contacts which are configured to break an electrical connection between input and output terminals on the circuit interrupting device when operated. The ground detector when combined with a circuit interrupter, triggers the circuit interrupter into a fault condition when the detector circuit detects the presence of a signal or a fault.

    摘要: An over voltage protection device for a GFCI having a voltage divider network connected across the line terminals of the GFCI, and an over voltage detecting diode connected between the voltage divider network and a gate terminal of an SCR. The voltage divider and diode cause a signal to be fed to the gate terminal of the SCR to trip the GFCI when an over voltage condition exists at the line terminals. The voltage divider is adjustable, with the sensitivity of the over voltage protection varying in accordance with adjustment of the potential from the voltage divider. In an embodiment of the invention, the circuit includes an indicator, such as a photodiode, which indicates the occurrence of an over voltage condition. In addition, a blocking diode is connected between the gate terminal of the SCR and a triggering terminal of an integrated circuit of the GFCI where the over voltage detecting diode conducts current to the gate terminal when an over voltage condition occurs, and the blocking diode conducts current to the gate terminal of the SCR when a ground-fault condition occurs.

    摘要: A GFCI device includes a latch assembly provided with a rigid electrically conducting bar connected thereto such that when a user presses a reset button the latch assembly is moved toward a pair of contacts provided as part of a reset circuit to initiate a reset operation. When the electrically conducting bar on the latch assembly connects the pair of contacts, the reset circuit is closed and an actuator is activated to place the GFCI device in the latched, reset, condition. If the GFCI device is correctly wired, the latch assembly enters the latched state. If the device is not properly wired no power is provided to the actuator and the device remains in the tripped, or open, state.

    摘要: A circuit interrupting device, such as a GFCI receptacle device, is provided that automatically resets itself when power is initially applied to the device, for example, when the device is first installed or when power is reapplied after a power outage occurs. When power is applied correctly to the line side of the device, as opposed to the load side, a voltage is generated that turns on a switching device. Turning on the switching device allows a low level of electric current to flow which, in turn, allows a higher level electric current to flow which closes the latching mechanism of the device and places the device in the reset condition.
