I haven't been able to find concrete stories either, though these[1] statistics might be an indication. It shows there's a few EVs per year that lead to a building fire, though sadly nothing further about source. So could be something else like battery.

That said there's been a campaign for several years trying to get rid of sockets for high current or permanent installations. I recently replaced both an electric water heater and mini split AC, and in both cases the previous appliance had used a socket and that was not allowed anymore.

Could well be they're just being proactive.

I really like the AU tri-prong system for this - high-current plugs/sockets have a physically larger ground connector.

This means you can put a low-current plug (small ground pin) into a high-current socket (large ground slot), but not the other way around.

Only downside I've found so far is that you can't use a high-current-rated extension cord to plug a low-current appliance into a low-current socket.

We’re not talking about high current anything, we’re talking about standard mains electricity.

By “high” I mean plugs rated for 240v16A, which is higher than normal Australian sockets (usually 8A).

		In most of Europe high current would be 32A, 16A is generally the standard (though I know Switzerland uses 10A and I believe UK plugs are rated for 13).
