In a DC circuit, are there any reasons for wiring overcurrent protection such as fuse, pptc, etc.... PHYSICALLY near the load(or inside it)? By wiring "physically near", I mean in the power wire going to the load, but near the end of the wire physically closest to the load.
As to an example of what prompted the question: Any wires exiting body controller of Tesla's model 3 are left exposed and vulnerable along the length of their run to the load and might need protection near the load as opposed to near the power source. Many such wires exit the body controller, in the form of wiring harnesses, and the body controller can selectively protect(from its end) any loads/branches by switching off the mosfet for that load. However, these mosfets are located INSIDE the body controller which leaves the load and remaining length of wire to the load vulnerable and unprotected. Consider what would happen if some other power source were to make contact along that length AFTER the mosfet switch and between the switch and the load; bypassing the protective mosfet switch. By protecting near the load as initially postulated this problem might be addressed.
So in a DC circuit are there any realistic scenarios where protecting physically near the load is worth the trouble/cost? How common are these problems? Doesn't have to be automotive related.
