A 240V mains socket (depending on jurisdiction) is expected to provide 3.6KW. That requires 15 amps of current, and (here in America) 14 AWG wire, 1.628mm thick

A 240V mains socket (depending on jurisdiction) is expected to provide 3.6KW. That requires 15 amps of current, and (here in America) 14 AWG wire, 1.628mm thick.
To source the same amount of power at 24V, you need ten times as much amperage, 150A, and 1/0 AWG wire, or 8.252mm thick. Much, much thicker, dramatically more expensive, and harder to handle.
And even with 1/0 AWG wire, you'll see a lot of voltage droop between the main panel and the outlet, which will be tens of metres away. A 20 metre run, at 24V and 150A will drop 7.5% of its voltage between the panel and the outlet.
