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

In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
