An electrified-cable system is disclosed herein. The system includes first and second wires each having a longitudinally-extending uninsulated region comprising at least a portion of the circumference of the first wire, and a longitudinally-extending insulated region comprising the remaining circumference of the first wire, and an insulating connector that couples the insulated region of the first wire to the insulated region of the second wire. The system is configured to form an electrical circuit from the first wire to the second wire through a carriage in electrical contact with the uninsulated region of the first wire and the uninsulated region of the second wire. A corresponding method is also disclosed.
