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.
