Abstract

Abstract A cable assembly for use in undercarpet wiring systems has a flat multiconductor cable encased in electrical insulation and an electrically conductive shield overlying the cable insulation, extending lengthwise with the cable and having successive extents which are respectively unsecured and secured to the cable. Electrical connection of the shield to the cable ground conductor is made redundantly at each such secured extent of the shield whereby physical continuity of the shield may be interrupted without interrupting electrical continuity of the shield to ground. Folded cable assemblies and methods for folding are set forth which facilitate cable directional change in wiring systems.
