Specifies requirements for electrical installations on small boats (viz boats with a maximum length of 50m).

This Part of AS/NZS 3004 specifies requirements for the design, construction and installation of electrical systems in recreational boats that have a length of up to 50 m, and are designed for use on inland waters or at sea. It is not intended to apply to small boats equipped with a battery supplying circuits for engine starting and navigation lighting only that are recharged from an inboard or outboard engine driven alternator.NOTES:1 Attention is drawn to the International Regulations for the Preventing of Collisions at Sea, 1972 (COLREG) as amended, which govern specific requirements for navigation lights for boats.2 Attention is drawn to regulations in Australia and New Zealand which govern specific requirements for the safety of electronic and electrical equipment; electromagnetic compatibility requirements; marine safety requirements; energy and water usage; telecommunications and radio communication requirements.3 For high speed boats, attention is drawn to the Australian National Standard for Commercial Vessels (NSCV), Part F: Special vessels, Section 1: Fast craft and the New Zealand Maritime Rules.This Standard applies to the following types of d.c. and a.c. electrical systems, individually or in combination:(a) Direct current systems which operate at a nominal voltage not exceeding 1500 V.NOTE: For example, for many small recreational boats this will be the main electrical system. Alternatively a boat equipped with an a.c. system as its principal electrical system may be also equipped with a d.c. system for navigation and communications equipment supplied from batteries.(b) Single-phase alternating current systems which operate at a nominal voltage not exceeding 1000 V.NOTE: Such a system may be the principal electrical power system of a recreational boat, or a system which may only be energized when connected to a shore supply, a.c. extra-low voltage, safety extra-low voltage etc. circuits may also comprise part of a single-phase a.c. system. A boat may also be equipped with d.c. system(s) as in (a) above.(c) Three-phase alternating current systems which operate at a nominal voltage not exceeding 1000 V.NOTE: Three-phase systems are likely to be the principal electrical power system of a recreational boat’s electrical installation. Such a boat may also be equipped with single-phase a.c. subsystem(s) and d.c. subsystem(s).Recreational boats whose electrical installation complies with the requirements of an international maritime classification society which is recognized by AMSA or New Zealand Maritime can be used to show compliance where appropriate with this Standard.NOTE: Exemptions based on the above paragraph must be supported by appropriate and current certification.
