Sparked:
I meant 20 amp service in the sense that each apartment in my building was provided with two 20-amp 120-volt circuits in the kitchen (240 volts across the two live slots of the two outlets, each duplex outlet on separate circuit breaker) and 20-amp 120 volt dedicated sockets for air conditioners in all bedrooms and the living rooms.
Each 20 amp "air conditioner" socket is on its own circuit breaker.
Now if they could have also re-done the bathroom supplies that would have been great. Our bathrooms are branched off the original existing 15-amp circuits. Mine, for instance gets its power from the lightbulb in the bedroom. Building was put up in the 1940s/50s
