Agreed with the two previous posts, actually the electrician should have tested the wiring with his calibrated test equipment to make sure there is no leakage or faults. Then he should have tested the two RCDs to make sure they do and don't trip at the right levels. If he's tested the wiring and the rcd he will know which are within specification and will not be using this binary trial and error technique.
If the rcd is not tripping with nothing connected, then with only the circuit connected and no appliances, it shouldn't trip even if it's well out of spec. As the wiring should be >1Mohm so an rcd would struggle to even notice that current.
