A ground/earth fault is a fault where part of the current returns back through a path other than the opposing hot or, more critically, neutral. A neutral/earth fault is dangerous because the circuit will continue to function normally, but the hot and neutral leg currents are imbalanced, and the chassis can become energized.
A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake-or may occur slowly, in the form of creep.eft-lateral strike-slip fault-a fault on which the displacement of the far block is to the left when viewed from either side. right-lateral strike-slip fault-a fault on which the displacement of the far block is to the right when viewed from either side.
