- A ground fault occurs between a grounded piece of equipment and an ungrounded conductor (wire).
- The equipment grounding conductor has a connection - due to the system ground - to the grounded conductor of the circuit. The current follows it because it is a low resistance path to the grounded conductor, which completes the circuit.
- The current reaches the grounded conductor and this effectively creates a short-circuit which causes the inverter to supply large a amount of current to the newly created low-resistasnce circuit.
- This high current flow will be identified by the inverter electronics, residual current device (RCD) or an overcurrent protection device (OCPD) as a fault, which will cause the one of them to trip and open (disconnect) the circuit. A RCD or inverter electronics will react quicker than an OCPD.
