Ground Post on a Power Center

[Alex2507]

My manual says that it's a ground reference point for ungrounded components. Is my DVD player an ungrounded component because it does not have a ground on the power cord and if so am I suppose to be doing something about it with this Ground Post?

Excellent question, Alex. I figured that it was for a turntable grounding wire, but I'm looking forward to what people have to say.

With me everything is my first time around so bear with me. I have some audio inter connects that have 2 balanced conductors and a shield. The shield is a bare copper stranded wire that pokes out of the cable pants at the waist section, if you can visualize that. The shield is not connected to the RCA connectors at all. I think I should connect this shield to the ground post in order to let any interference drain to ground.

Does this soune right? Forgive my impatients on this. I'm chomping at the bit over hooking up an external 2 channel amp. If I knew where you guys lived there would be knocking at your door.

Thanks,
Alex

Your DVD player has a 2 prong cable because it is double insulated, the chassis is not connected to ground.
That grounding terminal is there in case you have a need, like when you get a ground loop hum, you can tie components to it for a common ground point that may help.

I almost get it. I think that means that if I have 2 grounded components plugged into 2 grounded circuits, I can run a ground wire from each circuit back to the power center for a 'common ground point'.

Another thing I think the ground post might be for is to provide a 'common ground point' for ungrounded circuits that grounded components are plugged into.

With the audio interconnects I did connect the shields to the ground post.
Nothing blew up.
