In a normal power distribution network there are successive circuit breakers each responsible fore the circuit that lies below them.(adsbygoogle = window.adsbygoogle || []).push({});

Now suppose i assume that there is a short circuit in my house then shouldn't the circuit breaker that lies above the MCB in my house, maybe an ACB or MCCB in one of the power distribution boards trip, and if we go higher then shouldn't the highest level circuit breaker trip, before any of the successive circuit breakers trip??

I know that my thinking is wrong, because in that case an entire city will lose electricity even when one of its residents has a circuit trip in their house. Can someone please correct my logic.
