What is a fault?

Fault:

  • an unattractive feature, especially in a person's character or a piece of work
  • a weakness or failing
  • responsibility for an accident or misfortune
  • to criticize for inadequacies or mistakes
  • a fracture in the crust of a planet or a moon, accompanied by a displacement of the crust along one side of the fracture

An electrical fault is where the electrical current goes where it is not intended to go. Usually this is the quickest and shortest return path to the electrical supply service. An electrical fault will trip breakers and blow fuses in the circuit as protection to stop the short circuit.
