1. An electrical system comprising: a generator; a plurality of electrical subsystems that each includes its own energy supply; and a plurality of consumers, wherein: at least one of the consumers, which is classified with an average safety classification, is suppliable with power from either one of at least two of the electrical subsystems; and at least one of the consumers, which is not classified with a safety classification, is suppliable with power from only one of the electrical subsystems, and the at least one consumer having an average safety classification is situated symmetrically between two of the vehicle electrical subsystems; wherein each of the plurality of electrical subsystems includes its own energy supply, wherein each of the energy supplies includes a battery, wherein the generator is coupleable to one of the energy supplies via an intelligent switch, which includes a switch function and a diode function, and wherein the generator is coupleable to another of the energy supplies via another intelligent switch, which includes another switch function and another diode function.
