That's just being silly, of course. You do realize that's exactly why there are multiple breakers of varying amperages?

But the idea is carried out that way in homes. Low voltage control circuits are used more and more for a number of reasons--some having to do with fire safety and energy saving.

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?
