I would be mildly annoyed at 110v in easy reach with metal with out an isolation switch.
So how does it work in the US then? Is there a law that everything needs to be isolated very well, no metal shells allowed or people just getting electrocuted from time to time
Never considered that Europeans don't know the wonderful sensation of 110v. It can vary from a slight tingle (it's not even tingle, but I can't describe it) to a "holy shit" moment that throws you back, depending on how and where you touched it and how much current flows. The great thing about A/C is the cycle, unlike a DC current which can lock your muscles and keep you from letting go.

Many European electricians - and plenty of non-electrician idiots like me - will have had 240vac shocks, which are probably similar just a bit more nippy and will get worse faster than 110vac. I think the human body is also a weird electrical resistor that goes down with voltage.

I'd not describe it as 'wonderful' or a 'slight tingle'. It's a pretty fierce bite. shocking is the word I'd use.

I'd think if I'd had a few and got used to it, or if i knew it was coming maybe i'd downplay that a bit. But i've tightened up my unplugging process now (dayglow tape) to be sure i've unplugged the right plug. It was enough to know I don't want another unexpected 240vac zap.

I'd be pretty east to wrap 2 loops and 1 . . . no , leave that to electroboom.
