Answer :
1) If electric fuse is overloaded it can cause a short circuit and may catch fire.
2) MCBs are switches which turn off automatically when there is an overflow of current or when current exceeds the safe limit.
2) When the switch of the MCB is turned on, the circuit becomes complete again and current flows uninterrupted.
