Preface

• Greater use has been made of illustrations and examples to promote understanding of common or difficult aspects, e.g. line diagrams, alternative overcurrent device locations, International Protection (IP) rating summary, switchboard access.
• Testing and inspection provisions have been updated in alignment with AS/NZS 3017, including provisions for periodic inspection in accordance with AS/NZS 3019.

Other major changes to the content of AS/NZS 3000:2000 include the following:

• (i) Revised or new definitions for—
  • electrical installation;
  • circuit;
  • basic protection (protection against direct contact);
  • fault protection (protection against indirect contact);
  • outbuilding;
  • isolation; and
  • competent person.

• (vii) Expansion of the use of residual current devices (RCDs) to all socket outlet and lighting circuits rated up to 20 A.
• (viii) Limiting the number of circuits connected to any one RCD to three.
• (ix) Requiring the division of lighting circuits between RCDs where the number of both RCDs and lighting circuits exceeds one.
• (x) Arc fault protection must be provided for all switchboards with a nominal supply rated above 800 A and should be considered for all other switchboards.
• (xi) Full size neutral conductors are required on consumers mains, multiphase submarine and final subcircuits subject to some conditions, for example overcurrent detection is fitted.
• (xii) Allowance for a voltage drop of up to 7% where a substation is located on the premises.
• (xiii) Installation couplers are recognised as a suitable method of connecting cables.

Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.

Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Web Shop at www.standards.com.au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue.

Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization.

We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover.

This Standard was issued in draft form for comment as DR 06001 to DR 06010.

PREFACE

A1

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee EL 001, Wiring Rules, to supersede, in Australia/New Zealand, AS/NZS 3000:2000, Electrical installations (known as the Australian/New Zealand Wiring Rules).

This Standard incorporates Amendment No. 1 (July 2009). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.

The development of this Standard has been based on the following considerations:

(a) Results of a survey of the electrical industry indicated that the industry wanted a document better suited to the present electrical regulatory structure, which flows more logically, is easier to understand, reinstates much of the guidance information removed from the 2000 edition and contains an increased level of diagrammatic representation of concepts, and more selected examples.

(b) Experience gained in the application of the eleventh (2000) edition as expressed to Standards Australia and Standards New Zealand.

During preparation of this Standard, reference was made to IEC 60364, Electrical installations of buildings (all parts) and acknowledgment is made of the assistance received from this source.

The presentation of this edition differs from previous editions of AS/NZS 3000 in that the Standard comprises two parts but with both parts bound as one document.

Part 1 provides uniform essential elements that constitute the minimum regulatory requirements for a safe electrical installation.

It also provides an alternative regulatory vehicle for Australian and New Zealand regulators seeking to move from the present prescription of AS/NZS 3000 in electrical installation safety and licensing legislation.

Part 1 satisfies the following objectives:

• It is generally complete in itself to avoid cross referencing to Part 2.
• It may be called up in regulation as a separate Part or together with Part 2.
• It provides 'high level' safety performance outcomes/conditions without prescriptive work methods that demonstrate means of compliance.
• It establishes an enforcement link to Part 2. Failure to comply with a work method provision in Part 2 would breach high level safety conditions of Part 1 unless an alternative mechanism is satisfied.
• It establishes the 'deemed to comply' status of Part 2, confirming that installations that comply with Part 2 comply with high level safety conditions of Part 1.

4

• It establishes 'deemed to comply' status of AS/NZS 3018, relating to simple domestic applications, and parts of other standards, confirming compliance with 'high level' safety conditions of Part 1.
• It maintains alignment with IEC 60364 developments at the level of essential safety.
• It provides a mechanism for acceptance of alternative design and installation practices that are not addressed, or are inconsistent with, those given in the 'deemed to comply' Part 2. This mechanism is intended to apply where departures from the methods in Part 2 are significant rather than minor aspects that remain within the flexibility of Part 2.
• It details responsibilities, documentation and verification criteria for designers or installers that seek to apply an alternative method to the 'deemed to comply' methods contained in Part 2.

Part 2 provides installation practices that achieve certainty of compliance with the essential safety requirements of Part 1.

It is primarily a revision of the 2000 edition to provide work methods and installation practices that are 'deemed to comply' with the associated performance outcomes/safety conditions.

Part 2 satisfies the following objectives:

• It may be called up in regulation in addition to Part 1 to reflect a range of regulatory adoption options.
• It incorporates and elaborates on all 'high level' performance outcomes of Part 1 with the addition of requirements and recommendations to clarify and support compliance.
• It establishes the 'deemed to comply' status of AS/NZS 3018 relating to simple domestic applications, and parts of other standards, confirming compliance with the work methods of Part 2 and the 'high level' safety conditions of Part 1.
• It generally retains the structure of AS/NZS 3000:2000, except that Verification (inspection and testing) has been moved to the final section of substantive text as it would be the last function performed in the formation of an electrical installation, and damp situations have been separated from other special electrical installations as they are the more commonly occurring of special electrical installations.
• New introductory selection and installation clauses have been included in Sections 2, 3, 4, 5, 6 and 7.
• It restores information from AS 3000—1991 as requirements, recommendations and examples of typical, effective compliant solutions.
• Emphasis has been placed on common, practicable and cost effective methods that achieve safety compliance, fitness for purpose and a level of good practice rather than overly conservative or obscure measures.
