Can you say a little about your grounding scheme?

Posted by PeterGV on July 2, 2004 at 08:03:02:

Can you comment on your grounding scheme, please?

For example, I believe that you mentioned that the Furutech FPA15s are isolated ground (despite your excellent photography I can't really see if the green grounding line on the back attaches to the brass frame ground band)...

Assuming the outlets are isolated ground, I assume the iso grounds get hooked together and then go back to the center tap on the transformer. Is that right?

And the frame ground... the box is grounded and that goes back to the incoming A/C ground? Is that right?

Or are the A/C (frame) ground and the transformer center tap ground connected? (and I didn't see provision for a second, separate, dedicated ground line into your box)

Sorry if this is a bone-headed question, but I'm trying to work through a design myself and I'm trying to ensure it properly accounts for the necessary safety aspects.

My design is a two piece layout with filters, transformer, GFCI in one box connected with a fat cable (twist-lock connector) and a rack-mounted distribution panel containing the outlets, bypass caps, and volt/amp/freq meter. I'm trying to figure-out the maximally safe and performing ground system for the distribution panel.
