A circuit breaker is to be connected in series in the circuit it is to protect.
Explanation:
Let us understand why do we need circuit breakers.
Circuit breaker is a protective device which will break the circuit in case of emergency like the appliance gets short or the wiring may get shorted in between. Also it is provided to cut-off electricity to a specific part of wiring in a house/building etc. for non-emergency situations, say for the purpose of maintenance.
Invariably it is placed in series with the live wire at the switch board or circuit breaker box, so that as soon as circuit breaker trips/switched off, no electrical wiring in the circuit it is protecting should remain live.
The mains circuit breaker is placed in series with the wiring of the dwelling unit and the Electricity incoming point of the Electric Supply Company.
The remaining circuit breakers are connected in parallel to each other to various distribution points/rooms. If connected in series, it will be impossible to isolate a section/part of circuit.
However, each circuit breaker is to be connected in series in the part circuit it is to protect.

The circuit breaker should be connected in series to the circuit that it is protecting it.

The circuit breaker is a device that helps to protect the circuit. In case of emergency the circuit breaker cuts off any live wiring in the circuit. This process will only be possible if the circuit is connected in series to the circuit.

In series circuit connection, current flowing in the circuit is the same. When the circuit breaker cuts off, all the current flowing in the circuit breaks.

Thus, the circuit breaker should be connected in series to the circuit that it is protecting it.
