All of the guidance that I am aware of for personal protective grounding of medium voltage circuits and equipment for maintenance is specific to substations and transmission and distribution circuits. Is anyone aware of similar guidance for medium voltage circuits and equipment in industrial facilities? Industrial facilities have similar substation and distribution circuits for which the previously referenced personal protective grounding requirements are applicable and can easily be applied. However, MV metal-clad switchgear, motor starters and motors in industrial plants often have insulated terminals and bus for which protective grounds cannot be applied. Many new MV switchgear designs include the means to install personal protective grounds during maintenance of the MV circuit parts. However, existing installed MV switchgears and motor starters do not have these provisions. Is there any guidance or best practices available for establishing an electrically safe work condition for MV switchgears, motor starters and motors when personal protective grounds cannot be applied?
