What is the difference between a ground fault and a short circuit?
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. It is caused when a “hot” conductor makes contact with a neutral or ground conductor. A ground fault is an accidental contact between an energized conductor and ground or equipment frame.
