This subpart contains requirements applicable to emergency power installations having a manually controlled storage battery, diesel engine, or gas turbine driven generator as the sole emergency power source.

The normal source for emergency loads must be the ship's service generating plant.

Manually started emergency lighting and power systems must be activated by one manual operation, such as the manual operation of a switch from an “off” to an “on” position, to cause the emergency system to supply its connected loads.

The activating means must be in the navigating bridge or in a location where the means can be controlled by the chief engineer.
