Patent ID: 7075310

Claim:
A self-contained device for testing for a wiring fault condition, the device comprising: an electrical connector having first and second contacts, the two contacts configured for establishing an electrical connection to the wiring; a first signal generator in signal communication with the electrical connector, the first signal generator configured to generate a signal on the wiring and to receive a reflected signal therefrom; a second signal generator in signal communication with the electrical connector, the second signal generator configured to generate a radio frequency signal on the wiring; and a user interface in signal communication with at least one of the first and second signal generators; wherein in response to the first signal generator sending a signal down the wiring, a reflected signal from a fault condition is received; wherein in response to the second signal generator sending a signal down the wiring, a radio frequency disturbance at the fault condition is generated; and wherein the electrical connector is configured for locally testing for a wiring fault condition via signal injection at an AC wall outlet.
