Except as provided in this subpart, electrical installations on vessels of 100 gross tons and over must meet the requirements of parts 110-113 of this chapter.
(a) The requirements of this section apply in lieu of subpart 111.10 of this chapter.
(b) If a generator is used to provide electric power for any vital system listed in § 169.642 of this subchapter, at least two generating sets must be provided. At least one required generating set must be independent of the auxiliary propulsion machinery. A generator that is not independent of the auxiliary propulsion plant must meet the requirements of § 111.10-4(c) of this chapter. With any one generating set stopped, the remaining set(s) must provide the power necessary for each of the following:
(1) Normal at sea load plus starting of the largest vital system load that can be started automatically or started from a space remote from the main distribution panel (switchboard).
(2) All vital systems simultaneously with nonvital loads secured.
(c) The adequacy of ship service generators must be demonstrated to the satisfaction of the OCMI during the initial inspection required by § 169.221 of this subchapter.
Demand loads must meet § 111.60-7 of this chapter except that smaller demand loads for motor feeders are acceptable if the cable is protected at or below its current-carrying capacity.
Each lighting branch circuit must meet the requirements of § 111.75-5 of this chapter, except that—
(a) Appliance loads, electric heater loads, and isolated small motor loads may be connected to a lighting distribution panelboard; and
(b) Branch circuits in excess of 30 amperes may be supplied from a lighting distribution panelboard.
Navigation light systems must meet the requirements of § 111.75-17 of this chapter except the requirements of § 111.75-17 (a) and (c).
In lieu of the remote stopping systems required by subpart 111.103 of this chapter, remote stop stations must be provided as follows:
(a) A propulsion shutdown in the pilothouse for each propulsion unit,
(b) A bilge slop or dirty oil discharge shutdown at the deck discharge,
(c) A ventilation shutdown located outside the space ventilated, and
(d) A shutdown from outside the engineroom for the fuel transfer pump, fuel oil service pump, or any other fuel oil pump.
An engine order telegraph system is not required.
