    Hello,

    A ground wire was torn during excavation. Can this be spliced or does a new wire have to be run?

    Thanks,
    Bill

    Need some more information to give anything other than a general answer, but any wire that is broken is allowed to be repaired. How it is repaired depends on what kind of ground wire it is.

    By "ground wire" do you mean a "wire in the ground" or a "grounding" wire? There are few "single" ground wires which could, or would, be where an excavator could damage them, unless it was doing something like interconnecting power line towers, or poles.

    It's a grounding wire (bare copper) that is run into the ground attached to grounding rods. It was torn by the excavator.

    Thanks,

    The conductor can be repaired, but, it must be repaired with an exothermic connection like a Cadweld or an irreversible crimp. It might be easier to just replace it from the panel to the first rod.

    Thanks,
    How do I achieve an irreversible crimp? This sounds easier than a weld.

    The ground wire should be so close to the building that he should have damaged the house at the same time. But, it should also be such a short route that replacing it would be easier than going to the trouble of locating a crimping tool and the splices.
