IEC 60092-507:2008

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 registered tonnage not exceeding 500 GRT, designed for use on inland waters or at sea. It is not intended to apply to small craft equipped with a battery supplying circuits for engine starting and navigation lighting only, recharged from an inboard or outboard engine driven alternator.
This second edition cancels and replaces the first edition published in 2000. The significant technical changes with respect to the previous edition are:
- DC, AC single phase, and AC 3-phase systems are now included in one document.
- The standard now specifies requirements for electrical installations relevant to all small commercial or leisure vessels up to 50 m or which have a Gross Registered Tonnage (GRT) not exceeding 500 GRT designed for use on inland waters or at sea.
