ABSTRACT:
A method of providing a secure, long-lasting electrical connection between the concentric neutral wires of a Underground Residential Distribution (URD) cable and a sacrificial anode. The invention provides for the prevention of corrosion of the neutral wires of the URD cable. The method comprises: securing a mold around the URD cable and the concentric neutral wires over the area of contact with the anode connecting wire; pouring a low-melt alloy into the mold to surround the URD cable so as to contact at least 50% of the surface area of each of the neutral wires and the anode connecting wire in the area of contact; and cooling the low-melt alloy to form a solid casting around the concentric neutral wires and the area of contact with the anode connecting wire, whereby a secure, long-lasting electrical connection is provided between the neutral wires and the anode.
