This British Standard gives recommendations for the design, installation
and maintenance of electrical equipment for the generation, storage,
conversion, distribution and utilization of electrical energy for all
purposes in ships of all descriptions, including, where relevant, inland
and harbour craft, but excluding ships of war.
NOTE For vessels smaller than 500 grt or with a length less than 50 m,
IEC 60092-507 provides a basic standard for small vessel electrical installations,
including direct current systems not exceeding 50 V and alternating current
systems not exceeding 250 V single phase or 500 V three phase.
These recommendations are intended to provide satisfactory operation
and safety, especially from fire and electrical shock, of installed
equipment and portable and transportable equipment which is intended
to be connected to the ship’s electrical distribution system. They relate
principally to requirements for the installation, utilization, inspection
and testing, but certain recommendations for the construction of
electrical and electronic equipment are included.
This British Standard is not applicable to the internal wiring of
manufactured apparatus that is not wired on board. It is not intended to
provide for every circumstance – those of a special character may
require appropriate advice.
