Maybe we in Europe benefit from 230V with half the amperage and not the grounding scheme? Seems to me that line noise would scale down by factor 2 when we get 15V from 230V instead of 110V when using "analog" transformers.

Yes, John, US residential service is center tapped, with a "true ground", ideally 0 Volts, a legacy of Thomas Edison's old DC system. And obviously, with split single phase, we also need to allow for load imbalances. It is not until just now that I realized that the European standard "neutral" was so lax, and put in the context of lightning, it would indeed make one think twice about creating the best ground path for one's apartment block!

So, why is it that Europeans on this board claim that their electricity is seldom (or never) a problem for them?

And what of "galvanic" issues in the "absence of ground"?
