Not OP, but my current home had a dedicated 50A/240V circuit because the previous owner did glass work and had a massive electric kiln. I can't imagine it was cheap to install, but I've used it for beefy, energy hungry servers in the past.
Which is all to say its possible in a residential setting, just probably expensive.
Yes, or something like a residential aircon heatpump will need a 40a circuit too. Car charging usually has a 30a.
Electric oven is usually 40a.
There’s lots of stuff that uses that sort of power residentially
