A cable having a conductor assembly containing at least two electrically insulated conductors, where the at least two electrically insulated conductors are cabled together longitudinally into a bundle and enclosed within an overall cover, preferably nonmetallic; a bare bonding/grounding conductor cabled externally over the overall cover of the conductor assembly with the same lay and in concert with the conductors cabled within the conductor assembly; and a metal tape helically applied to form an interlocked armor around the cabled conductor assembly and bare bonding/grounding conductor. The bare bonding/grounding conductor is a similar size to the insulated conductors present in the conductor assembly and is in intimate contact with the inner curves of the convolutions in the interlocked metal tape armor along a substantial length of the cable. The armor and bare bonding/grounding conductor act in concert to provide a metallic sheath assembly which has an ohmic resistance value equal to or lower than the ohmic resistance requirements necessary to qualify as an equipment grounding conductor. In addition, an electrically insulated grounding conductor may be cabled within the conductor assembly to provide a redundant grounding path.
