I could be wrong, but I recall hearing that some of the more powerful PW transformers couldn’t get a UL tag not because of the plug or double grounding, but because they put out too much power. I just looked at my Z and one of my ZWs. Neither one had a UL tag.

I have the same understanding. The VW (same design as the ZW) was UL listed at 150W, but the ZW, despite exactly the same in terms of isolation and construction, was not because it was "too powerful" for "toys"
