More or less: what the RCB (residual-current breaker) does is to
sense a difference in current flowing between the phase (aka "hot")
and the neutral conductor. If there's a difference, there must be
some current flowing to ground (possibly through you, but hopefully
through the ground conductor) -- that means there is a path to
ground (not necessarily a short, though). Then the RCB trips.

But this is becoming somewhat... OT I guess :)
