                         Subpart 112.05--General
 
Sec. 112.05-1  Purpose.


    (a) The purpose of this part is to ensure a dependable, independent, 
and dedicated emergency power source with sufficient capacity to supply 
those services that are necessary for the safety of the passengers, 
crew, and other persons in an emergency and those additional loads that 
may be authorized under paragraph (c) of this section.
    (b) No load may be powered from an emergency power source, except:
    (1) A load required by this part to be powered from the emergency 
power source;
    (2) A bus-tie to the main switchboard that meets Sec. 112.05-3; and
    (3) Emergency loads that may be necessary to maintain or restore the 
propulsion plant, such as control systems, controllable pitch 
propellers, hydraulic pumps, control air compressors, and machinery 
necessary for dead-ship start-up.
    (c) Other loads may be authorized by the Commanding Officer, Marine 
Safety Center (MSC), to be connected to the emergency source of power to 
provide an increased level of safety in recognition of a unique vessel 
mission or configuration. When these loads are authorized, the emergency 
power source must--
    (1) Be sized to supply these loads using a unity (1.0) service 
factor; or
    (2) Be provided with automatic load shedding that removes these 
loads and operates before the emergency generator trips due to overload. 
The automatic load shedding circuit breakers must be manually reset.
