WASIR 2021 - Important information for electrical contractors



After an extensive review process, Western Power and Horizon Power have announced the release of the Western Australian Service and Installation Requirements 2021 (WASIR). This was communicated to electrical contractors by Western Power via email on 30 July 2021.

The WASIR supersedes the WADCM. 

Members should read and apply these requirements to all new consumer electrical installations as soon as practical but no later than six months from the date of publication, which was 1 August 2021.  WASIR clause 2.4 'Application', provides additional specific detail on the date of compliance and exemption criteria options.

Sections 11, 12, 13, 14 and 15 of the WASIR should be studied in detail, given the number of changes that directly affect new, altered and/or upgraded connections.

A more detailed description of the changes and the transitional path from the now superseded WADCM to the new WASIR is available on the Western Power website.
