Distribution Switchgear

As specifications are under continuous review, everyone associated with the design, manufacture, application and operation of switchgear should ensure that they consult with the latest edition of a relevant specification. They can verify this by checking the yearbook of the standards organisation. If they do not do this, then there is a danger that they will not comply with tenders or standard operation instructions and may put themselves into an illegal situation. The following standards are listed for guidance only and the yearbook should be consulted to ensure that the copy being used is up to date.
