Where can I pickup earth ground in my house? I am trying to setup some ground planes between parallel tracks. My house has PEX supply piping. I do not desire going into the service box. Can I use the center prong as a source for earth ground?
I am not sure why but the power strip for my train board has a terminal on the outside with a "Green" nut on it. Do you think this would be a source for earth ground? Note the terminal where the power cord goes in.
