I do not know exactly what an RCD does, but from about the year 2000, every fuse in the fuse cabinet must include a Ground Fault Interrupter circuit. A GFCI works by measuring the current leaving one side of a power source (the so-called "live" or "hot wire"), and comparing it to current returning on the other (the "neutral" side).

The output neutral should not be connected to the earth in this design. Not having a transformer- The output neutral does not need to be grounded because it follows the source neutral and lacks a transformer. To supply the output''s neutral connection, the secondary star point (D/Y) of the isolation transformer must always be grounded.

In a solidly grounded system, the connection of (usually) the neutral wire to ground at the supply source means that a complete circuit will be formed when a line-to-ground fault occurs.
