What should a lineman do after testing underground cable for charge?

After testing underground cable for charge, the proper procedure is to ground it after testing. Grounding the cable is essential for safety, as it helps to ensure that any residual charge or potential electrical energy is safely dissipated into the ground. This action minimizes the risk of accidental electric shock to workers who may be handling or approaching the cable later. Grounding creates a path for any stored energy to flow safely away from the cable, making the work environment safer.

In addition to safety, grounding can also protect equipment from damage that can occur from unexpected voltage or discharge. While disconnecting the cable or leaving it alone may seem like viable options, they do not adequately address the need for ensuring the cable is safe to approach or work on afterward. Wrapping the cable in tape does not eliminate the risk presented by any residual charge and does not provide protection against potential hazards. Therefore, grounding is the most effective and responsible action a lineman can take after testing.
