Abstract: A circuit breaker that functions like a double pole double throw (DPDT) switch is used to isolate the commercial power grid from an external power source. When in the “on” position the circuit breaker serves as a main power input circuit breaker allowing power from the commercial power grid to feed into existing wiring. In the “off” position the commercial power grid is disconnected and isolated from the existing wiring. Instead, the switch mechanism is connected to an external power source such as a generator. The generator can be safely operated without risking power backfeed into the commercial power grid.

Abstract: A device to be monitored plugs into the event counter apparatus which, in turn, plugs into a power source. The event counter apparatus monitors the flow of power from the power source, such as a wall outlet, to the device to be monitored. Each time the device to be monitored is powered on, current flows through the event counter apparatus. The current flow is detected and logged as an event. Event counter apparatus internal circuitry maintains a count of the number of times a device is powered on and off. The count is displayed on a display window of the event counter apparatus. The event counter apparatus may also include self-calibrating circuitry that stores a profile of the device's typical operating characteristics. The stored profile acts as a outside the fingerprint is detected an alarm can be activated to inform an observer to an anomalous status.
