Discrimination Discrimination is an important factor in an electrical installation. This is achieved when only the protective device which is nearest to the fault interrupts the circuit. Consequently, only the smallest possible part of the installation in which a fault occurs will be out of service. When applying fuses, it is easy to obtain discrimination, independent of the brand used. There are also no upper prospective current limitations above which discrimination can not be achieved. 
If the ratio between the fuse ratings is 1 : 1.6, complete and reliable discrimination can be easily and cheaply achieved. Even, using different brands gives no design limitations. Applying fuses gives: INSTALLATION DESIGN CONVENIENCE
