> MO a not-tiny house should have several sub-panels: Kitchen (enough to run the big stove + ~100A, but every outlet it's own 20A circuit) This seems like crazy overkill. Certainly there are kitchen appliances that devour power, but... what? Assuming an electric stove/oven, you really just need one dedicated circuit for that, and then everything else can run off another circuit. If you expect to use a microwave often, you might want it on its own circuit, but everything else you might have (blender, mixer, toaster, coffee/espresso machine, electric kettle, etc.) will run just fine on a single circuit. And regardless, you don't need a sub-panel for this. All of these can run just fine as separate circuits off your main panel.
