That might very well be, but I have touched 240V AC accidentally, and I'm fine. Don't think that would still be the case for 400V DC, whether it counts as "low-voltage" or not.

EDIT: After reading a bit, it seems that the "what is more deadly" discussion regarding AC/DC is much more complicated than I thought, so the above might very well be false...

240V AC peaks at 340V and most systems would rate 400V DC as being pretty similar.

Significant risk of shock, not much risk of arcing.

Above 220/240 it’s typically required a person be certified and wear certain fabric types to minimize hazards.
