Grounding

Many years ago I heard that it was sufficient to ground your equipment in the center screw of a wall socket?

Presently my G is run to a metal rail on balcony which is set in concrete.

Any recommendations on how to best ground ones equipment when living in an upper floor aptment?

Thanks all---R

First, I'm not sure what it is that you are referring to that you want to connect to an external earth ground point. Are you talking about grounding the chassis of the equipment, which would normally be grounded anyway via the AC safety ground pin of the power plugs (assuming they are 3-prong plugs)? Or are you talking about connecting the signal grounds/circuit grounds of the system to earth ground?

In either case, though, I agree with Ralph/Atmasphere that if your equipment is properly designed you are unlikely to be accomplishing anything constructive by adding extraneous ground connections. In addition, you would probably be introducing a code violation, and possibly serious safety hazards as well. See the upper part of page 8 of this paper.

+1 to the latest comments by Mofi and Jim (Jea48), including and especially the second paragraph in Jim's post. The intent of that terminal is to allow connection of the ground wire of a turntable. It is not intended for connection to an earth ground. See the diagram on page 6 of the manual.
