Why are fuses connected in parallel to loads??

The problem is that,the loads i.e electrical machines working due to electricity,can bear upto a certain flow of current through it,when the current flowing through it crosses that limit,it gets worn out due to excess heat produced due to the current flow.

So,what we do is that connect a fuse wire of measured ampere i.e current flowing through it in series with the loads,now the fuse is designed in such a fashion that when the ampere measured in it,flows through it,it melts immediately and the wire breaks hence the circuit breaks as well,so current will be flowing no more through the loads.

But if the fuse wire was connected in parallel,then on breaking the of the fuse wire,the circuit would not have been broken,rather current flowing through the load have been increased,leading to a massive disaster.
