Abstract: A device and method of wrapping an electric cable used for grounding a utility vehicle to minimize its electrical impedance to 60 Hz alternating current. Electrical cable is wrapped around an array of four spools that are arranged so as to form two parallel, closely-spaced planes with the axes of the spools defining the planes. The distance between the spools of each plane is larger than the distance between the planes so that the cable, when wound, forms long, parallel segments. By reversing the direction of the cable and keeping the segments parallel and close to each other, electrical currents induced in these segments cancel each other and keep the impedance in the wrapped cable minimal. Preferably the cable wrapping path begins between the two pairs of spools and continues counterclockwise outside both of the pairs of spools. The path then proceeds between the spool pairs and then clockwise outside of both pairs to the starting point.

Additional support has been provided by employing resilient spaced apart strips along a track upon which the one or more flexible cables and support band slide. The resilient strips center the travel of the one or more flexible cables and support band and minimize rocking motion and vibration. Still further the one or more flexible cables and support band are arranged with respect to a robotic media library so that a single length of the one or more flexible cables and the support band will serve a range of lengths of the library.
