House Wiring diagram for three Phase

I have updated the previous video for the 3 phase wiring diagram because there is a little bit left to join the RCCB in the neutral line connection.
I can't edit the previous file, so I'm uploading it again.
The link of the previous file is shown below this video.

Iñ three phase house service connection, can we ground neutral wire separately?
