WebAug 18, 2024 · 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). Here, too, the circuit is "short," in that it has bypassed the circuit wiring, so a ground fault can technically be defined as one type of short circuit. And, as with any short circuit, the ...
