The following table shows a typical layout for a residential 200 amp (40 breaker positions) main breaker panel, installed 22 Jun 1994. This residential installation also includes a Tesla Powershare sub-panel which allows an electric vehicle that supports vehicle-to-grid/load sharing to supply power to the residence in the event the main grid fails. If the vehicle, a Foundation Series Cybertruck in this case, is plugged into the system the switch-over will be automatic. It will not (as of 2025) be separate battery backup system (UPS), unless you don't mind them rebooting randomly. Appliance clocks may also need resetting, although if there is a decently sized electrolytic capacitor in the circuit it might be OK.
