That would be per 20 amp breaker. Sockets are usually ran in series off of the breaker. Now in some industrial settings they can use 25-30 amp breakers. Or in some household setting they can use only 15 amp breakers. Also outlets can be lower power than a breaker because many are ran in series. Also remember power strips are also usually only rated for 15 amps.
Best bet, put a meter on your outlets.
ps most houses I have come across have a 200 amp main. But remember there is an AC, refrigerator, washing machine, dryer all being power hungry. However if you need a 220/240 outlet for a limited time you can usually steal from your dryer.
