the current rating of the fuse must be equal to the load
because the fuses melting point disconnect the circuit if
the current load becomes greater than the specific rating.
in high ruputer capacity fuse,the fuse able to carry1.2
over the rating.meaning 20% more.MCB rating calculation is
to know how mush the consuption load and according to that
cal.we decide the rate of MCB from the catalog rating of
CB, must be more than the load.DONT FORGET THE SHORT
