fuel must be adequate to keep the generator running, in emergency

conditions, for the period specified for the vessel concerned - whilst the

radiol satcom equipment is being run from that generator.

Individual equipment fuses

All radio and satcom equipment will have a protective fuse

somewhere in the power supply circuit - usually at the point of entry

into the equipment, or in the power supply cable leading to the

equipment. You should carry spares for every piece of equipment, making

sure that the spare fuses are:

• The correct rating (current).


• The correct type - e.g. T (anti-surge); S (slow-blow); F (fast); FF {very
  fast}.


• The correct physical sizeltype (e.g. cartridge or bayonet).
