Every time I switch on one specific circuit breaker, the residual-current device (RCD) switches off. I've disconnected every device that's on the group, and even took out all light bulbs, but the problem doesn't go away.
I think there are two options now, either there's something wrong with the circuit breaker, or with the wiring (there are three other groups that share the RCD, but I have no problem with those, so I think the RCD is OK).
Are there other options, and how do I find out where my problem is?
(I know next to nothing about electrical wiring, so I hope I got the terms right.)

First choice: Call a licensed electrician. Second choice: Find all the outlets and lights which are affected by the breaker. Start with the one closest to the panel. Open them all up and visually inspect. If nothing is seen, turn on the breaker with everything opened up - does it still trip. Sometimes movement in the boxes will re-position wires and remove a short.
If you still have a problem, start removing sections from the circuit - i.e., disconnect them from the line. Start in the middle - check breaker if no more tripping your problem is down line from that point. Get the idea?
