Abstract
A cable network and a method for protecting the cable network against a serial arc are disclosed. In particular, a 42 V vehicle network for a motor vehicle is contemplated. The cable network includes a supply line connecting a voltage source and a load. The supply line includes two cable runs that are connected in parallel. Each of the cable runs contains a fuse therein. In the event of a cable defect in one (first) of the cable runs, all of the current flows via the other (second) cable run. This prevents an arc from being formed at the cable interruption in the first cable run. The fuses are preferably in the form of electronic components, which positively disconnect one another as soon as one component is activated due to a fault.
