Abstract: An electrical cable includes a solid-core wire; an outer sheath surrounding the solid-core wire; and a connector attached directly to each end of the cable. The electrical cable may have a code marked on the outer sheath of the cable near each end of the cable in which the code is individualized for that particular electrical cable. The code may also be marked at intervals along the length of the cable, for example about every one to five feet. The cable may have at least eight solid-core wires, each wire being at least 24 gauge or heavier; an outer sheath surrounding the at least eight solid-core wires; and a factory/field-attached RJ45 connector attached directly to each end of the cable, wherein each connection is factory or factory-quality tested. The cable may be at least 60 feet long.
