Indicia-coded electrical cable

An electrical cable comprising:

• a metal sheath that envelops at least two internal conductors,
• at least two different conductor indicia visible on the internal conductors, the conductor indicia being representative of a type of cable or of a purpose for which the cable is intended to be used, and
• a sheath indicia comprising at least two different representational sheath indicia visible on the sheath and representative of the same type of cable or the same purpose for which the cable is intended to be used as is represented by the conductor indicia.

A cable comprising:

• a tubular conductive sheath having inner and outer surfaces, the inner surface of the sheath defining an internal passage sized and configured to enclose a conductor,
• a first visible indicia displayed on the outer surface of the sheath and representing a gauge of the conductor, and
• a second visible indicia displayed on the outer surface of the sheath and indicating a type of cable.

A cable comprising

• internal electrical wires that have insulative coverings bearing colors that are representative of a predetermined function of the cable,
• a helically wound metal sheath that envelops the wires, and
• sheath colors that are visible on and at multiple locations along the sheath and are the same colors as the colors borne by the insulative coverings of the internal electrical wires.
