Electrical discrimination occurs when a protective device near a fault or short comes on and keeps the other circuits working properly. Discrimination can either partially block a fault from disrupting other systems or completely block it, depending on the type of protection device that is installed.
Fuses or circuit breakers are the main sort of protective devices used in homes. If a fuse blows or a breaker trips in one specific room or device, the rest of the home is protected from the issue that caused the reaction. Proper wiring of a house or building is imperative to ensure that the structure's protective devices will work properly to protect against faults.
