And that is sort of my point - there is nothing that changes sharply between 999V and 1500V in terms of lethality, but years ago the line was drawn in the sand between LV and HV, at a nice round number to set a working limit that seemed high enough not to be a problem to normal loads.
I suggest that perhaps for higher powers, for charging lorries and so on, that may well now become a decision worth revisiting.
I am well aware that for years various bits of equipment have generated far higher voltages inside - the microwave oven for example at 4 or 5kV with a lot of ripple on the cathode of the magnatron, or the EHT on the old CRT tellies (at about 20kV, but current limited)
But for working on AC wiring, 1000V is the magic phase to phase voltage in IEC land. UL limits are a bit different, but similarly limiting.
