This standard BS 6626:2010 Maintenance of electrical switchgear and controlgear for voltages above 1 kV and up to and including 36 kV. Code of practice is classified in these ICS categories:
29.130.10 High voltage switchgear and controlgear
This British Standard 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.
NOTE 1 This standard is not applicable to explosion protected switchgear and controlgear. Inspection and maintenance of electrical apparatus in explosive gas atmospheres is covered in BS EN 60079‑17.
NOTE 2 This British Standard 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”.
