BS 6626:2010: Maintenance of Electrical Switchgear and Controlgear for Voltages Above 1 kV and Up to and Including 36 kV: Code of Practice

BS 6626 is a British Standard which gives recommendations and guidance for the maintenance of electrical switchgear and controlgear having a rated a.c. or d.c. voltage above 1 kV and up to and including 36 kV. BS 6626 doesn't apply to explosion protected switchgear and controlgear. See BS EN 60079-17. BS 6626 covers applications above 1 kV. Voltages below 1 kV are considered to be low voltage in line with the European Commission Directive 73/23/EEC [1], known as the "Low voltage directive".
