alt Hacker NewsCorrect me if I’m wrong, but doubling the volts doesn't change the amps, it doubles the watts. Watts = V*A.

Doubling the volts halves the amps. P = I * V indeed.

Yes; I assumed 30A was minimum requirement for 240V service in US. Apparently I was wrong, 20A 240V is apparently normal. So in theory you could use a pre-existing 20A 120V circuit's wiring for a 240V (assuming it was 12/3 cable). And apparently 4-wire is now the standard for 240V service in US? Jesus we have a weird grid.
