I guess it might just be a UK health and safety thing. Like you I've touched 230v a couple of times as a kid but can't say it's exactly pleasant.
This blog post lists the reasons professional builders in the UK could use 230v and an RCD but generally dont.

- jakobegger 9y agoThanks for the link! It looks like there's another important safety feature: the center of the output side of the transformers is connected to ground --> this means that you have two phases that both have only 55V to ground. I imagine that accidentally touching an exposed wire with a voltage difference of 55V is a lot less dangerous than 230V. I love HN. You learn new stuff every day.
