Building and Energy recently released an updated version of the WA Electrical Requirements (WAER)

The new WAER will apply to all new electrical installation designs commenced after 1 February 2024.

An amendment to the WAER does not apply retrospectively to electrical installations for which design or construction has commenced or for which building contracts have been signed prior to the date of publication of the amendment.

Key changes in the updated version include:

  • Section 2
    • Replacement of WA Distributions Connections Manual (WADCM) references with WA Service and Installation Requirements (WASIR) – applicable to Western Power and Horizon Power.
  • Section 3
    • New table included that sets out ownership and responsibilities for each component of service apparatus.
  • Section 7
    • Expanded scope from only high voltage (HV) installations to large-scale installations that include solar, battery and wind turbine installations which exceed the upper limits (200kVA) covered by Australian Standards.
    • Outlines design requirements, design submissions and certifications for all large-scale installations that must be provided to the Network Operator.
    • Final testing and ‘as commissioned’ certification that must be provided to the Network Operator (for network connections) and installation owner/operator (for network connected and standalone systems).
