Re: [CAD_CAM_EDM_DRO] Re: Gecko 5V supply

On DC power circuits neither side is grounded. So both the + or - buss has zero potential to ground. Years ago when I was running
diesels generating DC power for electrolytic hydrogen it was normal to feel the bolted buss connections looking for hot spots.
It took watching someone else doing this a few times before starting to do it. Just don't grab both busses at the same time.
I would have to do some checking before I did this on electronic systems.
