Vov generators connected to distribution board supply
The first thing to consider is that if there is no return path, there will be no "fault" current. (One of the basic principles of a safety supply).
The second thing to consider is as follows:
There is a supply side and a load side to an RCD.
The return path for a fault on the load side has to be via the supply side of the RCD for the RCD to trip.
If the fault point and return are both on the load side, the RCD will not trip as there is no difference in current at the points in the circuit it is measuring to sense a difference in current.
