  1. As a comparision, here in Finland pretty much all single family houses have 3 phase 230 V service (nominally "240 V" but intentionally run at exactly 230 V due historical reasons). And in addition to your usual circuit breakers building code requires all new wall sockets to have fault detection (50 mA leakage to ground will trip the circuit). The only exception is wall sockets designed for single use only for devices that are not moved (e.g. freeze, refridgerator and other devices you really want to keep powered all the time) where fault detection is not required. And the voltage between 3 phases is around 400 V. Most homes have service connection through three 35 A fuses that means max is 3*35A*400V = 42 kW in total. That's enough to run 10 kW stove, heat water and the house and all the electronics in the whole house.
