As an electrician I'm crying to see that many mistakes at once.The cable cross-sections for the supply of the automatic circuit breakers (above) are wrong. In Germany there are 3-pin prefabricated copper bridges for this. The blue wires for the N busbar have been cut too short without any reason. There should be more reserve loop behind the circuit breaker. While the work looks good, it is technically critical.That electric panel looks very dangerous, one thin wire to power every circuit?
