This document provides guidance for the specification and selection of the appropriate approach and for the planning and the execution of the maintenance of low-voltage switchgear and controlgear and their assemblies having a rated voltage up to and including 1 000 V AC or 1 500 V DC, and designed for a nominal frequency of the incoming supply or supplies not exceeding 1 000 Hz. This document explains how the use of preventive maintenance improves the efficiency and lifetime of built-in components and consequently the assemblies themselves. All parties (specifiers, owners, designers, manufacturers, maintenance personnel) involved with low-voltage switchgear and controlgear assemblies can benefit from this document. This document provides guidance on the safety precautions for personnel designed to carry out maintenance services, with the aim to minimize the safety risks, optimize service continuity (power availability) and contribute to the environment of a low-voltage switchgear and controlgear assemblies. It recognises there are different approaches to maintenance, e.g. scheduled maintenance, condition-based maintenance and predictive maintenance. This document does not consider specifically corrective maintenance but many of the recommendations included would apply when carrying out corrective maintenance. It provides additional recommendations to comply with validation requirements in IEC 60364-6.
