Jon, I measure zero voltage with or without load. Can you please explain why a leakage current in that spot even with y rated caps would be dangerous. I ask this to understand this issue not as a challange. Thanks, Tweaker

In the US standard electrical wiring you have one "hot", "neutral", and "ground".
Neutral and ground are tied together in the breaker box, this should be the only place these two are tied together. As the ground wire is for safety and not to be used to carry current.
When a load is put on the circuit there would be a voltage drop in the neutral wire from the point of the load to the ground tie point breaker box. This voltage could also be measured from ground to the neutral at the outlet. It's not going to be much, but in the case of high voltage transients it could be quite high if the transients are generated at or near the outlet.
Good explaination. I have found 1uf Y2 caps . I believe but would have to look again that they can take transient 5 kvs. Any reason not to use these 1 uf caps, or maybe up to 5 or 10 in parallel? They can take the voltage in an extreame situation, won't catch fire. The current thing I don't understand. Tweaker
For those of you asking how a safety cap differs from a normal
capacitor.
