1 Scope
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.
NOTE For vessels smaller than 500 gross tonnes (GT) or with a length less than 50 m, BS EN 60092‑507 provides a basic standard for small vessel electrical installations, including direct current (DC) systems not exceeding 50 V and alternating current (AC) 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 installation, utilization, and inspection and testing,
although recommendations for the construction of electrical and electronic equipment
are also 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 –
in some cases, specialist advice is required.
