It's not my consensus! Yes, the building ground is likely to be noisy,
unless you actually connect directly back to its earth spike. Even then, the
wire you use is an inductor and may have noise induced in it.

I think the issue is far more about electrical safety than EMC. Of course
you are quite right about a Faraday cage not requiring an earth connectio

Warning Will Robinson - Brian is not an EMC expert.
Agree with Herr Gremmen about the referencing of equipotential points - this
was critical for my employer's current chamber because it was sitting next
to a machine shop and a HALT chamber

As for the purpose of operation, EMC chambers need no grounding.
The shielding property happens by conduction of the shield material the chamber
is made from.
But as soon
as a grounded one.

Hi All
Which is the best to use
Hi All
Which is the best to use?
Ground each EMC chamber via an earth spike or back to the transformer of the
supply to the building?
Which is best practice?
