The electrical code requires short circuit rating (SCCR) of an equipment to be selected so that it would not subject the equipment to extensive damage when it has a short circuit. According to the electrical code the SCCR is the prospective symmetrical fault current at a nominal voltage.

Blutooth,
To see the answer to your question, see if you can answer this simple question without looking at mine:
Is there a potential difference between the grounded DC and AC side of the system under normal operating condition?
And the answer is.... NO, sorry I couldn't wait.
So, why is...
Blutooh,
Only the ground electrodes of the two systems are connected together. The ground electrodes are in direct contact to earth, thus creating earth connection for both systems. There are normally no other current flowing through them into the ground, except for the systems leakage current...
Blutooh,
The depicted diagrams are layout of a grounded inverter system (vs. an ungrounded system). In such a system, the AC and DC sides are isolated from each other via a built-in isolation transformer. Therefore, you have a separately derived (inverter) system where the DC grounded conductor...
