Wiring Rules 2017

The wiring rules are changing

The Australian Standard AS/NZS3000 (the wiring rules) is being updated and will be released later this year.

In June to July 2017 the Electrical Safety Office held the Wiring Rules Roadshow in 36 information sessions in 22 locations across Queensland.

To help the electrical industry prepare for the upcoming changes have been developed a series of films which highlight the major changes to the wiring rules.

Hi I'm Mark Pocock from the Electrical Safety Office. As you are aware the Wiring Rules are being updated, so I wanted to talk you through some of the key changes to safety switch requirements and mechanical protection of cabling, that will appear in the next edition due for release later this year.

We have been a strong advocate for the use of safety switches. The new edition supports this approach with increase in safety switch requirements, now a must on all final sub-circuits in domestic and residential installations.

The existing requirements for maximum three circuits per RCD, minimum two RCDs still remain for domestic and residential electrical installations.

For non-domestic and non-residential electrical installations 30 milliamp RCDs shall be installed on all lighting and socket outlet final sub-circuits less than or equal to 32 amps.

30 milliamp RCDs should be installed on all final sub circuits less than or equal to 32 amps supplying fixed wired electrical equipment.

30 milliamp RCDs shall be installed on all final sub-circuit supplying fixed wired electrical equipment that may represent an increased risk of electric shock. This could be environmental conditions such as wet areas and the type of electrical installation or processes being conducted there.

For home care medical installations the RCD requirements for medical equipment in-home care medical installations shall comply with AS 3003.

The Wiring Rules refers to AS 3003, so if you work on home care electrical installations then you will need to refer to this standard. It is noted that AS 3003 has been completely revised with a new edition published in 2017.

With an increase in a number of allied trades working in the vicinity of electrical cables it is most important that mechanical protection of cabling is provided.

More detailed requirements the mechanical protection for cables installed within a ceiling space wiring systems near building surfaces and wiring systems likely to be disturbed are included in the new addition.

Hi I'm Mark Pocock from the Electrical Safety Office. As you aware the Wiring Rules are being updated so I wanted to talk you through the transition arrangements. In Queensland a licensed electrical worker who performs electrical work on an electrical installation must ensure that the electrical installation, to the extent that is affected by the electrical work, is in accordance with the Wiring Rules.

Transition from one wiring rules addition to another can impact an electrical installation. For example electrical work may have commenced, been designed or quoted on under the former edition. For a smooth transition to the new edition, the preface to the Wiring Rules recommends it not be applied on a mandatory basis before a date at least six months after publication. Work underway at the time of publication of the new Wiring Rules may therefore not meet some of the requirements in the 2017 edition. The enforcement commencement date for the new edition is yet to be determined. The Electrical Safety Office will seek advice from other Australiana safety regulators ensuring one agreed date across Australia. It will be available in the coming months.

Hi, I’m Mark Pocock from the Electrical Safety Office. As you are aware the Wiring Rules are being updated so I wanted to talk you through some of the key changes to the requirements of sleeving of conductors and the segregation of different services, that will appear in the next edition due for release later this year.

There will be changes to the content of sleeving of existing earthing, bonding and live conductors this recognises existing installations where bare earth green insulation for live conductors has been used. When alterations, additions or repairs are carries out that result in new teminations or junctions then the existing conductors can be sleeved with the colours defined in the new clauses. Requirements for different electrical installations have been altered in a new edition to provide more clarity. This includes changes to the common enclosure and segregation requirements. These changes relate to conductors for different installations or for individual occupancies forming part of a single or multiple electrical installation that are installed in a common enclosure.

Recessed luminaires and pool area installations

Hi I'm Mark Pocock from the Electrical Safety Office. As you are aware the Wiring Rules are being updated so I wanted to talk you through some of the key changes to recessed luminaries and pool area requirements that will appear in the new edition, due for release later this year. The recessed luminaire requirements have been rewritten for the current edition to make it easier to understand. Recessed luminaries will have new classifications for example luminaries require markings that will indicate if they can be installed against or covered with flammable material or simply be used in areas where there is thermal insulation.

The standard also includes ancillary equipment such as drivers and transformers. To help explain this approach in the new edition will have a series of new drawings and tables that explains each classification and location where luminaires can be installed. There are also some changes to the requirements for pool area installations, in particular bonding arrangements and the location of electrical equipment. To assist with the update there is a diagram depicting an example of bonding arrangement for pools and spas. There is a new requirement that where a pool structure is conductive the connection point shall be installed and bonded to the installation earthing system, regardless of the requirements specified. The requirements prohibiting switchboards of the requirements specified. The requirements prohibiting switchboards being located in any classified zone still exists, with the scope of this requirement being extended to electrical generating systems and an electrical distributors’ equipment.
