Dear Student
Ritu did not choose a right wire fuse, because in the home appliance there are 6 A or 16 A current flow, maximum current can drawn is 20 A as give in the query, When all appliances will be ON then there will be overloading, but still it will not reaching beyand 100 A, so 100 A fuse is of no use, So that fuse should be near to 20 A to 30 A specification.
