Question

why are mcb
preferred over electric fuse

Answer 1

Mcbs are preffered than fuses because when a fuse is blown out then we should replace it with new one but if we use mcbs we don't need to replace we can just turn on the switch in case it drips.

Answer 2

mcb are preferred over electric fuse because when an electric fuss is burnt we have to replace it with a new but when a mcb cuts off the current we only have to reset it
this is main reason why MCBs are preferred over electric fuses
