If kettles were continuous loads we’d have to reduce from 16A to 10A (2200W) or 8A (1800W). Schuko are rated for as little as 1h of 16A but for a kettle that’s plenty, they’re done in a minute or two.
German stoves are connected to at least 2x10A, newer installations (as in since the 70s or such) all provide 3x16A. Not actually three-phase they’re still 220V appliances. Whether the outlets, light etc. are on different phases differs widely.
