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?=20

Josef, The process of using branch circuits with multiple fuses (or =
