Differential circuit breaker jumps by ground spliced neutral
The first thing is not to assume that such a cable is earth, it can be neutral and not insulated. I have found up to phases without isolating so the lack of isolation determines absolutely nothing
The second is to analyze how it is connected. As Nastor says, both phase and neutral must come from inside your home
If this cable is really ground it is obvious that the differential will act as it must return by neutral, not by ground
This is the typical theft of current. When using earth as neutral of the company there is no return to the meter and this does not mark what corresponds. Maybe they just did it with the bell. There are many cases in which the entire installation is in those conditions with the consequent risk to the physical integrity of the users.

Your judgment is somewhat rushed, without asking if the whole house is left without its equipment and lights.
The other thing is that if the meter reaches the phase and the neutral, it will integrate the energy correctly, because the current measurement is made in the phase and not in the neutral.
Hello Ennio, this man recently acquired the house and if it were not for trying to improve the installation (putting a differential) or he would not have noticed the event, he is a victim of an illuminated electrician. Do you have any idea how many people steal light by that method? ? How many accidents are there for that reason? Don't forget that it's just a comment from me. Regards

If the comment that they steal current by grounding the neutral, you are in error. Another intervention must be done to steal energy, which we are not going to deal with here.
You know what I mean and the way it is done and I am not accusing this consultant, he is just a victim of trade union bad practices. Many times I have been asked to intervene in both electricity and gas, two extremely delicate areas where saving can result in misfortune.
In addition, all the artifacts would have stopped working and not only when the bell rang.
Sorry to comment on the comments, but we must make the interventions clear.
What I interpret is that the source of the bell has the phase of the company and as neutral it has physical ground, so when it rings the bell, it unloads the ground and the differential jumps, not the rest of the house, that is more than clear. ..the problem is only with the doorbell. As for the comments, that's what they are for; Propose different opinions. The solution has already been provided by Nastor, Ennio and Elektomaq, which must be changed to the neutral of the company.
Hi Thank you all for commenting, and participating in solving the problem. I think that as Ennio says when the neutral was cut, they used the ground wire, which causes the short circuit and causes the circuit breaker to jump. Since the problem is only with the bell (the rest of the installation seems to be fine), I will follow the wiring to see if I can solve it by connecting the neutral properly and removing the ground. Thank you for your point of view, then I will comment as follows.
