Abstract
IEC 60092-302-2:2019 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.
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.
The manufacture and/or assembly can be carried out other than by the original manufacturer.
This document does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, which comply with the relevant product standards.
This first edition cancels and replaces the fourth edition of IEC 60092-302 published in 1997. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) this document has been renumbered to fall in line with IEC 61439 (all parts);
b) this document has been restructured to fall in line with IEC 61439 (all parts);
c) the creepage distances have been modified;
d) the references to non type tested assemblies (NTTA) have been removed;
e) non-applicable tables have been removed;
f) the applicability of IEC 61439 (all parts) annexes have been identified.
g) specific requirements that were detailed in IEC 60092-302:1997, covered under 7.6.101 have partly been moved to 60092-201.
