The result is confusion among users of this technology as to:
When a short occurs in an electrical circuit, extremely high currents flow. Because these currents will be much greater than circuit design parameters, they can damage circuit components and pose fire and other safety hazards. Protection mechanisms such as fuses and circuit breakers are designed to be the weak link: They break the circuit to minimize or prevent such damage. While simple in concept, the science of short-circuit protection is a complicated one, requiring careful coordination of component withstand ratings and the interrupt capabilities of the chosen protective device(s) with the available fault current.
