What is fault locating?
 
Fault locating finds grounded shorts (nicks) or opens (breaks) in private electrical lines. A grounded fault is when the damaged wire makes direct contact with the ground.


What does the fault locating process include?

  • Both ends of the faulted electrical line must be disconnected by the homeowner or contractor.
  • The wires are tested to find faulted wire or wires
  • The fault is located
  • Once a fault is located it is dug up by the homeowner or contractor, the wires are cut and both end are stripped. The wires are re-tested in both directions
  • The testing and fault locating continues until all faults are located
  • It is the responsibility of the homeowner or contractor to repairs the faults.
