N-set, the "neutral" wire is certainly referenced (connected) to ground. The usual "ground" wire is redundant, and this is why it often causes problems with hi-fi, also why a dedicated bleeder that does not go to the mains ground will sometimes do the trick for "residual" hum.


Definitely is, if I understand correctly somewhere at the power plant. This must be taken into account when designing
equipment IMHO-->R. Morrison's  classics on the grounding.
We tried to find the NG bound with my electrician. It's neither in my panel, nor in the main power entrance to the building
(I have a luck of a "dedicated" run to my apartment directly from the main house panel, ommiting all other apts).
I'm not sure what the practise is to get the ground in my region, but John seems to shed some light:

In the case of Europe, this DB ground comes from a tap taken from the incoming cable armored sheath.  This is designed to handle fault currents only.
It used to be grounded only at the feeder transformer but this has been relaxed but you are not allowed to fit your own ground.  Besides, it is incredibly noisy.


As for CMBR I intentionally resigned from it after an approval of the electrician. I want just a simple old-style fuse (costing me a fortune since I wanted Siemens,...)

Cheers,
