Errr, short-circuiting to ground will cause a RCD to trip immediately - that's what they're there for. You will generally have one RCD on the entire fuse board, and then individual circuit breakers for each branch.
If that's really how they do that - one RCD for a bunch of circuits then I have to retract my words, a ground fault would cause a whole bunch of circuits to lose power.
It seems crazy to me, but if they do that, then they do that.
