(a) (1) Electric power sources, their transmission cables, and their associated control and protective devices must be able to furnish the required power at the proper voltage to each load circuit essential for safe operation; and (2) Compliance with paragraph (a)(1) of this section must be shown by an electrical load analysis, or by electrical measurements that take into account the electrical loads applied to the electrical system, in probable combinations and for probable durations. (b) (1) Each system, when installed, must be— (i) Free from hazards in itself, in its method of operation, and in its effects on other parts of the rotorcraft; and (ii) Protected from fuel, oil, water, other detrimental substances, and mechanical damage. (2) Electric power sources must function properly when connected in combination or independently. (3) No failure or malfunction of any source may impair the ability of any remaining source to supply load circuits essential for safe operation. (4) Each electric power source control must allow the independent operation of each source. (c) (1) Each generator must be able to deliver its continuous rated power; (2) Generator voltage control equipment must be able to dependably regulate each generator output within rated limits; (3) Each generator must have a reverse current cutout designed to disconnect the generator from the battery and from the other generators when enough reverse current exists to damage that generator; and (4) Each generator mus
