UDS manual - Edition 10 (PDF 6.1Mb - Large file)
Last updated: September 2013
This 10th edition of the Underground Distribution Schemes (UDS) Manual supersedes all previous editions of this Manual.
The implementation of the 10th edition of the manual shall apply to projects from the 22nd of October 2013 as follows:
Project designs issued with a DIP package prior to the publication of this edition of the UDS may be completed in accordance with the requirements of the 9th edition of the UDS Manual if completed within Western Power's issued information package validity period, that is within 6 months from the date of issue. (Refer clause 18.104.22.168).
Where work has commenced or formal contracts to undertake UDS works were signed prior to the publication of these requirements Western Power may grant permission, on receipt of an application, for exemption from these amended requirements. Exemption will not be granted where there is a safety concern.
The amended information contained within 10th edition Manual and subsequent amendments is not retrospective from the date of publication unless an existing development or part thereof constitutes a safety issue as determined by Western Power.
This manual contains the information required by developers and their electrical consultants to allow them to undertake the electrical reticulation of new subdivisions.
