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, 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.
