5.1 Scope and application

This section sets down the principles and minimum requirements for maintaining the supporting structures for overhead lines.

An electricity entity should have a maintenance system that achieves a minimum three-year moving average reliability against the incidence of failure of 99.99 per cent a year.

Special consideration should be given to poles in areas of higher risk, such as cities and towns.

This section does not apply to safe access for work on poles. For this information, see the Code of Practice for Electrical Work under the Electrical Safety Act 2002 (PDF, 788 KB).
