However if an RCD trips, it indicates a wiring fault. The most common cause is incorrectly connected earth wiring. The second most common, is water ingress, but I digress ... What is actually happening when power is restored is some current that should be flowing in the neutral wire is finding a way to flow in the earth wires instead.
Many electricians have no real understanding of how electrical systems work, and just follows rules they were taught in college. If your installer has wired the system incorrectly, they are likely unaware that they made an error and therefore won't be able to correct it. Finding an electrical engineer that can understand why the RCD is tripping and what needs to be done to correct it will be a challenge.
