fuse is use to protect the equipment from abnormal condition

Answer / stm619

Actually Phase, Neutral concept comes only in A/C, whereas in DC, we have only +VE , -VE. FUSE is not used not becoz of havind a fuse at phase supply , but becoz to prevent the consequences of Neutral break.

For consequences of Neutral break pls refer...

Neutral should never be cut. It should always be connected.
