This is a fun subject. Carrying the house wiring analogy to the extreme, that
would mean that every light, every outlet, every electrical devise should have
its own fused electrical circuit. Furthermore. every circuit that is switched
should have a separate relay so that the switch is powered from one circuit &
it energizes a relay that in turn energizes the light, etc. Shouldn't the relay
circuit also be fused? What if the short is in the relay circuit?

Josef,The process of using branch circuits with multiple fuses (or breakers
inindustry) is called protective discrimination.If done properly, the lower
rated fuse will rupture before the higher ratedone above it in the chain.
