(b) An electrical power system that complies with the requirements of §§111.10-4, 111.10-5, and 111.10-9, in subchapter J of this chapter;
(c) A final emergency power source, as defined by §112.01-20 in subchapter J of this chapter, with sufficient capacity to power the loads listed in §112.15-5 in subchapter J of this chapter for three hours; and

(b) The generator circuit breakers must be interlocked to prevent the generators from being simultaneously connected to the switchboard, except for the circuit breakers of a generator operated in parallel with another generator when the installation meets §§111.12-11(f), and 111.30-25(d) in subchapter J of this chapter.
(k) Switchboards and distribution panels must be sized in accordance with §111.30-19 in subchapter J of this chapter.
[CGD 85-080, 61 FR 928, Jan. 10, 1996; 61 FR 20556, May 7, 1996]
(1) Meet Section 310-13 of the NEC (NFPA 70) except that asbestos insulated cable and dry location cables can not be used;
(3) Meet §111.60-1 in subchapter J of this chapter for cable and §111.60-11 in subchapter J of this chapter for wire.
(o) Ampacities of wires must meet Section 310-15 of the NEC (NFPA 70), or other standard specified by the Commandant. Ampacities of cables must meet table A6 of Institute of Electrical and Electronic Engineers (IEEE) Standard 45, “Recommended Practice for Electrical Installations on Shipboard,” or other standard specified by the Commandant. Ampacities for Navy cable must meet NAVSEA Design Data Sheet (DDS) 304-2 “Electrical Cable, Ratings and Characteristics” as appropriate.
(p) Conductors must be sized so that the voltage drop at the load terminals does not exceed 10 percent. Table 1 to §120.340(p) indicates the size of conductor required for corresponding lengths and steady state (stable) values to obtain not more than this voltage drop at the load terminals of a two conductor circuit.
