After the operation of the RCD, the electrician disconnected the neutral wire - is it dangerous?
All the sockets did not work, the electrician checked them, everything is in order, I did not find the reason for the operation of the RCD. Disconnected the neutral wire. Is it dangerous?
Zero is probably confused with grounding, so the electrician turned off zero (in theory, this is ground). In any case, you need to find the cause of the current leakage, which is why the RCD trips. Try disconnecting the entire load from the RCD and cocking the lever, if the operation did not happen, the reason is in the wiring and you need to look for a malfunction. If the RCD trips after disconnecting the entire load, replace the RCD.
