This British Standard gives recommendations and guidance for the maintenance of low-voltage switchgear and controlgear having a rated voltage up to and including 1000V a.c. or 1500V d.c.
This standard is applicable to stationary and movable switchgear and controlgear with or without an enclosure. It is also applicable to switchgear and controlgear for use under special service conditions, possibly with additional recommendations, for example in ships and rail vehicles.
This standard also gives recommendations on safety precautions for personnel carrying out maintenance. Guidance on the levels ofmaintenance necessary for and also procedures for the maintenance of the principal components within equipment is included. Guidance is also given on the assessment of the on-going suitability of equipment.
It also gives recommendations on the direct replacement of parts and, where this is not possible, guidance on device substitution.
This standard is not applicable to switchgear and controlgear used in potentially explosive atmospheres.
NOTE Inspection and maintenance of electrical apparatus in explosive gas atmospheres is covered in BSEN60079‑17.
