241-253 depending how the transformer feels.
In no country is there 230V. It's 220 or 240 nominal.
You use a muscle which isn't tensed up. Only those in the path of the current are tensed. Assuming it's not going through your head, your brain can still make a decision. And it's not painful for muscles to tense up. You need a very high voltage to hurt (as in burn).
It used to be they put 50mA as the only ELCB in the fusebox. 30mA was for the little plug in ones for sissies and lawnmowers.
This was back in the 90s, when I saw other people's fuseboxes. I've never had breakers in any house I've lived in and never will. They're a pest.
Rating A B C D etc. The number of ms it's over 30mA before it cuts out.
