Electrical installations in ships - Part 302-2: Low voltage switchgear and controlgear assemblies - Marine power

IEC 60092-302-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 60092-302-2:2025 defines the specific requirements of low voltage marine power switchgear and controlgear assemblies (mpsc-assemblies) as follows:

- stationary assemblies with enclosure for which the rated voltage does not exceed 1 000 V AC or 1500 V DC;

- assemblies intended for use in conjunction with the power generation, distribution and conversion of electric energy, and for the control of electric energy consuming equipment.

Due to the marine application and the risks associated with loss of power, additional safety factors have been applied to minimise the risk of failure, such as applying an additional safety factor on clearance distances.

This document applies to all assemblies whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity.

Either the manufacture or assembly, or both, of the MPSC assembly can be carried out by
