what is diffrances between fuse and breaker protection?
which one is best?
Answer Posted / aamirali
Fuse and Breaker both are used for protection against short ckt current. Fuse is used for low voltage protection say homes, shops, hospitals, schools etc. While ckt breaker is used for mostly high voltage side say factories, substations, power grid, whole buildings etc.
If we use ckt breaker instead of fuse it is not economical, maintenance & operating is not easy also rating. Fuse is easy to operate in low voltage side.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
