Post Subject: Whose ground?Posted by floobydust on: 2/20/2009

By definition and code, a separate non-current carrying ground is required for all outlets. In every house I've lived in, the ground is a separate thick copper bar that goes deep into the ground (the earth outside the house) and that is the ground connection for the house electric system. How can this can be considered dirty, other than the dirt that the copper bar is earthed in? It is certainly not dangerous if wired correctly but can be if it is not.

If the PP2000 is properly configured as an isolated power source (which I would suspect is the case), neither the neutral or hot lines from the power outlet are carried thru to it's output. By law, the non-current carrying ground line must be carried thru, otherwise the device could not carry a UL rating and end-users could be at risk. Ground loops in equipment can occur for many reasons, but lifting one or more grounds "may" cause an unsafe condition depending on how the equipment is wired internally.

There is good news however, so far, I've not gotten pregnant... but I think it's more of a plumbing issue.
