The arrangement shown in Fig. 1.7 incorporates some common features.
The emergency switchboard has two sections, one operating at 440 volts and the other at 220 volts. The 440 volt supply, under circumstances, is taken from the main engine room switchboard through a circuit breaker A. Loss of main power this breaker to be tripped and the supply is taken over by the emergency generator when started through a An interlock prevents simultaneous closure of both breakers.
A special feeder is sometimes fitted so that in a dead- ship situation the emergency generator can be connected to the main switchboard. This special condition breaker would only be closed engine room board was cleared of all load. i.e. all distribution were open. Selected machinery within the capacity of the emergency generator could then be operated to restore power, at which stage the special breaker would be disconnected.
The essential services supplied from the 440 volt section of the emergency board depicted include the emergency bilge pump, the sprinkler pump and compressor, one of two steering gear circuits(the other being from the main board), and a 440/220 volt three-phase transformer through which the other section is fed.
Circuits supplied from the 220. volt section include those for navigation equipment, radio communication and the transformed and rectified supplies systems Separate sets of batteries are fitted for temporary emergency power and for a low pressure The former automatically supply emergency lights and other services not connected to the low-pressure tem Batteries for the radio are not shown.
The switchboard and generator for emergency power supply installed in one compartment which may be heated for starting in cold conditions. The independent and approved method of automatic starting (compressed air, batteries or hydraulic) should have the capacity for repeated attempts. And a secondary arrangement such that further attempts can be made within the 30 minute temporary battery lifetime.
The emergency generator is provided with an adequate and Independent supply of fuel with a flash point of not Less than 43ºC(110ºF).
