41PR-6157 POWER LINE COMMUNICATION OVER GROUND AND NEUTRAL CONDUCTORS OF PLURAL RESIDENTIAL BRANCH CIRCUITS ABSTRACT OF THE DISCLOSURE Power line communication over plural residential branch circuits accommodated by creating a signal coupling inductive impedance in a tie conductor electrically interconnecting the grounded neutral bus, to which the branch circuit neutral conductors are commonly terminated, and a ground bus commonly terminating the branch circuit ground conductors, such as to support voltage signals propagating on the ground conductors with respect to the neutral conductors of the branch circuits. This inductive impedance is created either by a signal coupling transformer linked with the tie conductor and driven by a signal transmitter, with signal receivers capacitively coupled across the branch circuit neutral and ground conductors, or is of a passive nature, which both transmitters and receivers capacitively coupled across the branch circuit ground and neutral conductors.
