BS EN 60092-507:2015
This standard BS EN 60092-507:2015 Electrical installations in ships is classified in these ICS categories:
- 47.020.60 Electrical equipment of ships and of marine structures
- 47.080 Small craft
1.1 General
This part of IEC 60092 specifies requirements for the design, construction and installation of electrical systems in small vessels, which have a length of up to 50 m, or which have a gross tonnage not exceeding 500 Gross Tonnes (GT), designed for use on inland waters or at sea. It is not intended to apply to:
-
small craft equipped only with a battery supplying circuits for engine starting and navigation lighting recharged from an inboard or outboard engine driven alternator.
-
recreational craft of less than 24 m hull length requiring to conform to the Recreational Craft Directive 94/25/EC Annex 1 Essential Requirements Part 5.3 Electrical systems, except for three-phase alternating current installations in such recreational craft which operate at a nominal voltage not exceeding AC 500 V.
1.2 Electrical systems
This standard applies to the types of DC and AC electrical systems described below, individually or in combination.
-
Direct current system which operates at a nominal voltage not exceeding DC 50 V. For many small vessels, this will be the main electrical system supported by batteries for engine starting, navigation lights, navigational aids and communications equipment, lighting and other DC power consumer or converter equipment.
-
Single-phase alternating current system which operates at a nominal voltage not exceeding AC 250 V. Such a system may be the principal electrical power system of a vessel or a system which may only be energized when connected to a shore supply. AC extra-low voltage, safety extra-low voltage, and other circuits may also comprise part of a single-phase AC system. A vessel may also be equipped with DC system(s) for equipment supplied from batteries as in 1.2 a) above.
-
Three-phase alternating current system which operates at a nominal voltage not exceeding AC 500 V. The three-phase system is likely to be the principal electrical power system of a vessel’s electrical installation. Such a vessel may also be equipped with single-phase AC circuits(s) similar to 1.2 b) above and DC system(s) for equipment supplied from batteries as in 1.2 a) above.
Concerning recreational craft of less than 24 m hull length referenced in 1.1 b) above, the following standards apply:
-
for direct current installations which operate at a nominal voltage not exceeding DC 50 V: ISO 10133 ;
-
for single-phase alternating current installations which operate at a nominal voltage not exceeding AC 250 V single phase: ISO 13297 .
For alternating current systems having voltages exceeding AC 250 V single-phase or AC 500 V three-phase, for direct current systems exceeding DC 50 V, and for vessels larger than 500 GT or with a length greater than 50 m, other standards within the IEC 60092 series apply.
Attention is drawn to regulations which govern specific requirements for navigation lights for small vessels.
Attention is drawn to the fact that, in some countries the EC Directives covering EMC ( 89/336/EEC ), low voltage ( 73/23/EEC ) and general product safety ( 92/59/EEC ) may be applied. In addition, Council Directive 97/70 applies to fishing vessels of 24 m in length and over, and Council Directive 98/18/EC applies to passenger ships. For high speed crafts, attention is drawn to the International code of safety for high-speed craft (HSC Code).
