Just a test - don't leave it that way .........

But not if the PC is connected via shielded CAT cable: the PC ground
(and the cable shield) will get noticable voltages from the AC filters
in the PC, and it might damage equipment on the other side of the
cable.


** Line filters are required to meet standards for ground leakage.
Got any idea what current level that is ?
How does it compare to ground loop currents?

FYI: MOVs must not connect to ground in an appliance.
