Went to look at a C/U change yesterday to be confronted with this.
Im not normally one to insist on a EICR before changing a C/U I usually just do the tests before removing the old one.
However in this case I can see troubles ahead....
Clearly there has been tripping issues with the upfront RCD, so the obvious solution was to bypass it.
Seems the only visible earthing is the gas pipe, makes it even more worrying...
(there is a DNO tail coming off the incoming sheath (TNS) but not connected to anything. And no obvious earth spike.
The light blue insulating tape makes me suspect a builder has been in to play, as builders always seem to use light blue insulating tape for some reason?...
