This part of IEC 60092 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 others than 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.
NOTE Individual devices and components include those that are covered by the IEC 60947 series.
