I'm not entirely sure what you're asking, but the term "grounding" is actually a misnomer and has caused much confusion in the electrical industry over the purpose of grounding/earthing and bonding. The primary concern of premises wiring systems is maintaing a low impedance path back to the source, not the earth. This is done via the bonding conductor, which is commonly called the grounding conductor.
Accidental contact between the grounded (neutral) conductor and grounding/bonding conductor is a fault that can be hazardous in some situations but I wouldn't go so far as to call it a "ground fault".
