I don't see the point of grounding one component to the copper filled box. The concept of the grounding boxes on the market is to create a common ground for all the components. All are wired to the box which creates a star-ground; they will have the same ground potential. This box is then plugged into the mains.
DIY Active Ground Box
I recently received a custom cable that has three loop-ground spades that are linked to the cable's shield. The cable was originally designed for phonograph use, but my customized version is being used in a digital to analog function. The manufacturer left the loop-spades in. The manufacturer said I could just use electric tape to "cap them off." The ground cables are not 100% necessary in this application. However, they are an exposed conductor. I know that I can enhance their performance by treating them as a floating shield by using an active ground.
I was thinking it would be cheaper and more practical to make my own. Does anyone have experience doing this? If so, can you share your design ideas?
The concept I have seen and want to build on, is making a wooden box that is coated internally with copper plates. Then use an IEC C14 socket to attach the ground lead to the copper plates via a solid copper cable. Then create a simple plug using a NEMA 1-15 connector where only the ground lead is connected.
Then insert banana plug sockets that also attach to the copper plates via a copper cable. Then connect the spades to the banana plug outlets.
Once this contraption is plugged into the wall socket, it should effectively attach to the house's ground.
Thoughts?

I like that you are thinking this way to begin with. It may not be the best approach, yet there is merit in the thinking. I agree with the previous poster as to what might be tried out. Even in a star grounding scheme, it wouldn't hurt to ground components one by one. If somehow there is trouble because of it, you will have a head start on the direction to look. |
