ABSTRACT:
A device to detect and control electrical potential polarities between two or more adjacent insulated conductor sections is disclosed. An amplifying circuit monitors the relative state of the polarities of the adjacent conductor sections and actuates a relay to change the same if a difference is sensed. The sensing function of the amplifying circuit is controlled by a switch member.
