ABSTRACT:
At a point on a residential branch circuit downstream from the service entry load center where the termination of the neutral conductor thereof is solidly clamped to ground and the ground conductor is terminated in electrical connection in common with the neutral conductor termination, a transformer is linked with one of the neutral and ground conductors. Downstream from the transformer, a capacitive coupler is connected across the branch circuit neutral and ground conductors. A transmitter of high frequency voltage signals is connected with either the transformer or capacitive coupler and a signal receiver is connected with the other thereof, such as to establish a communications lin between the transmitter and receiver using the branch circuit neutral and ground conductors.
