A ground fault is a type of fault in which the unintentional pathway of the straying electrical current flows directly to the earth (to the ground). … Like other types of short circuits, a ground fault causes the circuit breaker to trip due to the uncontrolled flow.

How do you diagnose a ground fault?

To locate a ground fault, look for continuity to ground on each circuit. This new analog ohmmeter will show infinite ohms when the conductor is not exposed to an earth ground. If the insulation is compromised and/or the copper is directly connected to ground the ohmmeter will indicate 0 ohms.
