    Abstract - (Show below) - (Hide below)

    Describes recommendations for the maintenance of electrical switchgear and controlgear having rated voltages up to and including 650 V. Excluding special maintenance requirements relating to explosion-protected switchgear and controlgear. Recommends procedures for maintenance of the principal components of equipment and gives guidance concerning replaceable parts. Includes guidelines on safe isolation procedures for work on systems operating at voltages up to and including 650 V, graphical illustration of some of the terms and definitions, example of a maintenance record card and information required from the manufacturer/supplier for maintenance of equipment.
