Also, it does not matter if it’s a wall wart or something else with a built-in power supply. The important thing is, for class-2 there has to be a double or reinforced insulation between mains circuits and touchable parts.

That’s for „double insulation“.</div><div class=""><br class=""></div><div class="">Ingo</div><div class=""><br class=""></div><div class=""><br class=""></div></body></html>
