Yes you can. The proper wiring of a switch is to bring the hot wire to the top of the switch terminal and connect the load to the bottom of the switch. When the breaker is turned off it disconnects the voltage from the top of the switch and the switch is then safe to work on. By not turning the breaker off, the voltage is present at the top of the switch which could subject you to a nasty shock if you come into contact with it.

No, the main breaker switch should be locked out in the off position to prevent accidental power restoration while maintenance or repair work is being done. Locking it in the on position poses a safety risk and is not recommended.
Yes, some electrical breakers can move to the off position when they trip. This is a safety feature to indicate that the circuit is no longer functional. To reset the breaker, switch it back to the on position, then to the off position before resetting it to on. If the breaker continues to trip, there may be an underlying issue in the circuit that needs to be addressed.
A trip switch, also known as a circuit breaker, works by detecting an overload or short circuit in an electrical circuit and automatically interrupting the flow of electricity to prevent damage or fire. When the circuit breaker detects an abnormality, it quickly switches off to cut off power and protect the circuit from further damage. Resetting the trip switch restores power once the issue is resolved.
Switch your main breaker off.
You may need to first switch it on before off.
Circuit breaker or switch
When the switch is turned off, the breaker trips to protect the electrical circuit from overload or short circuit. This happens because the sudden interruption of the electrical flow can cause a surge of electricity, triggering the breaker to trip and cut off the power to prevent damage to the circuit.

To reset the breaker in your apartment, locate the electrical panel, identify the tripped breaker (it will be in the "off" position), switch it to the "on" position, and then test the power to ensure it has been successfully reset.
To properly add a breaker to a panel, first turn off the main power switch. Remove the panel cover and identify a free slot for the new breaker. Connect the breaker to the panel's bus bar and then connect the circuit wire to the breaker. Secure the breaker in place and replace the panel cover. Finally, turn the main power switch back on.
