Eric, the isolation capacitor does not serve a purpose in this discussion. It would ensure that no DC gets through.
You assumption that no DC power exceeds the input power measured at the mains should be accurate. It would be very difficult to keep excess DC flowing at a higher level for the long periods associated with the PWM.

First off, the insertion of an isolation capacitor between the main grid transformer and the plug takes care of your "short circuit" problem. And then there's the possibility of injection of RF also, also capacitatively coupled into the plug lines. Assume that the three-phase power coming into the transformer has not been tampered with (seems like a safe assumption, but you never know ;). Assume as well that Dave is correct that at the transformer there will be a DC short to ground. With these assumptions, am I correct in drawing one of the two following conclusions? No hidden DC to the E-Cat resistors exceeded the power measured at the mains; or Rossi or an associate intentionally added an isolation capacitor (i.e., tampered with the mains). Eric
