Here in the uk we have a maximum of 3000watts (13amp fuse in a mains household plug).... How do they run a large motor without the fuse blowing
Bigger items must be hardwired, I guess... You've got a whole different system there with a single hot providing 230V @ 50 Hz... Here's an excellent video showing how a typical UK household panel works: https://hackaday.com/2019/04/14/a-pe...l-power-panel/
You'll note a 40A 230V B40 breaker to the right of center there... That's 9200Watts! There are also B6, B16 & B32 breakers in that panel. Looks like the full range includes: 1, 2, 4, 6, 10, 13, 16, 20, 25, 32, 40, 50, 63, 80, 100, and 125Amp.
In North American residential panels, we typically have 2 120V 60Hz legs 180 degrees out of phase that give 240V across the pair and each leg to Neutral gives 120V. See more here: Understanding your Electrical Service, 120V vs. 240V.
Typical residential 120V circuit breakers are 15, 20, 25, 30, 40, 50Amp
Typical residential 240V circuit breakers are 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 125Amp
Typical residential 240V main breakers are 50, 100, 150, 175, 200Amp
And then, of course, there's the rarely encountered residential 3-Phase; but I'll stop there!
