A circuit interrupting device includes line and load terminals and an interrupter electrically coupled therebetween, the interrupter having open and closed conditions. The device also includes a fault detector configured to detect a fault in an electrical signal in the load circuit. When such a fault is detected, the fault detector causes actuation of the interrupter to the open condition. A communication interface is adapted to receive a remote test command signal, and a processor generates, in response to receipt of the remote test command signal, a simulated fault in the load circuit, such that the fault detector attempts to cause actuation of the interrupter to the open condition. The processor determines whether or not the fault detector successfully caused actuation of the interrupter to the open condition in response to receipt of the remote test command signal, and if not, generates an alarm signal indicative of a malfunction.

Ground fault circuit breaker with remote testing capability

A circuit interrupter electrically connects a line terminal to a load terminal in a closed condition and electrically disconnects the line terminal from the load terminal in the open condition. A controller includes a fault detector configured to detect a fault in an electrical signal in a load circuit, such that when a fault is detected on the load circuit, the fault detector causes actuation of the interrupter to the open condition. The controller is adapted to receive an off command, and in response to the off command, generate a simulated fault in the load circuit, such that the fault detector causes actuation of the interrupter to the open condition, such that one and the same interrupter is employed for both fault tripping and commanded tripping.

Remote operated ground fault circuit breaker

Modular wireless switch system for use in an aircraft, which may include an integrated LED backlight. The system includes a master module having a power supply, a switch, and a wireless communicator configured to communicate a switch state. The system also includes a slave module connectable to the master module, which has a second switch and which is configured to communicate a second switch state using the wireless communicator. All wireless communications may be handled by the master module using a protocol such as ZigBee&#x2122;. All communications from the slave module may be transmitted to the master module via a wired bus. Additional slave modules are connectable to the bus as desired.
