Abstract

An arrangement for supplying electrical power to at least one load arranged along a power supply line, preferably in motor vehicles, is characterized by having a power supply facility that has at least one input for a supply voltage and at least one output for the supply voltage and a testing device, by the testing device being designed to test an output for the supply voltage to establish whether a short-circuit, i.e. a resistance of too low a value, exists at this output, and by the power supply facility having a switching device and being designed in such a way that a supply voltage fed to it is switched through by the switching device to the output tested by the testing device only when the test has established the non-existence of a short-circuit. This allows the power supply to be maintained if a single fault occurs.
