The fuses protect the lines upstream to the next protection device. That doesn’t mean every house could max out their breaker at the same time. Just like you can’t pull the max amperage on each circuit breaker in your panel without popping the mail breaker.
To answer your question, most American homes I’ve seen have 240V at 200A. Some older homes have 100A.
I’ve got a 400 amp service. The power company buried me a parallel run to my meter that feeds a 200 amp panel in the house and another in my shop. Will I ever come close to pulling that? No
