The use of either AS/NZS 3439 or AS/NZS 61439 for low voltage switchgear and control gear assemblies has been extended until 25 November 2022 in Queensland.

Both AS/NZS 3439 and AS/NZS 61439 series of standards are referenced in the Wiring Rules, meaning either standard can be used to comply with installation requirements.

AS/NZS 3439 was superseded by AS/NZS 61439 on 24 May 2021, five years after the latter was published, to allow switchboard manufacturers time to update switchboard equipment to the new standard.

MEA has been in discussion with the Electrical Safety Office on behalf of electrical contractors advocating for this extension.

During the transition period, ESO will not prevent switchboards compliant to AS/NZS 3439 being sold, unless specific safety issues are identified.

Electrical contractors must install according to the manufacturer’s instructions and the Wiring Rules.

Repairs, alterations, or additions to existing switchboards (by adding components or parts), is not considered sale of a new switchboard. Adding a complete self-contained prebuilt switchboard module, however, is considered sale of equipment.
