How did you figure out you had a voltage leak to ground at the converter? I suspect that I have voltage bleeding off somewhere in my system and am currently (Ha,ha) trying to find it.

John:
In the hospital we used a special electrical safety tester to measure electrical leakage that had switches and a meter to disconnect the ground from the power source, and then to measure the AC current flowing through the equipment ground wire to a good ground. The maximum current allowed in the hospital was 500 microamps (0.5 milliamps). GFI's for general electrical equipment trip at 5 milliamps, so I would think that would be the maximum for consumer devices.
You could do the same test by disconnecting the grounded wires to the convertor, then using a DVM measuring AC current between the convertor case and a good ground. To make sure you are getting a good reading, and there are no unnoticed ground paths, I would disconnect power to the convertor, and measure the resistance between the convertor case and ground. The reading should be infinite ohms (open circuit) with the grounds disconnected. I would THEN apply power and do the leakage check.
