AS/NZS 3000:2007, also known as the "Australian/New Zealand Wiring Rules," is a joint standard that outlines the requirements for the design, construction, and verification of electrical installations. The primary purpose of the standard is to ensure the safety of people, livestock, and property from hazards such as electric shock, fire, and physical injury that can arise from electrical installations.
AS/NZS 3000:2007, also known as the "Australian/New Zealand Wiring Rules," is a joint standard that outlines the requirements for the design, construction, and verification of electrical installations. The primary purpose of the standard is to ensure the safety of people, livestock, and property from hazards such as electric shock, fire, and physical injury that can arise from electrical installations.
The 2007 edition is structured in a two-part format within a single document:
Part 1: The Core Safety Requirements. This part details the fundamental principles and minimum regulatory requirements for a safe electrical installation. It covers essential elements such as:
Protection against electric shock: This includes basic protection (against direct contact) and fault protection (against indirect contact).
Protection against overcurrent and earth fault currents: This addresses the use of protective devices to prevent damage from faults.
Protection against thermal effects: This ensures electrical equipment does not cause excessive heat that could lead to fires.
Control and isolation: Requirements for devices that allow for safe disconnection of power.
Protection against abnormal voltages.
Part 2: Installation Practices. This part provides detailed guidance on how to meet the essential safety requirements laid out in Part 1. It offers practical installation methods and procedures, covering topics like:
Selection and installation of wiring systems: This includes cable types, current-carrying capacity, and voltage drop.
Selection and installation of electrical equipment and accessories: This provides specific rules for items like socket outlets, lighting, and appliances.
Earthing arrangements: The standard specifies the requirements for earthing systems and conductors.
Special installations and locations: This includes rules for damp situations, such as bathrooms, swimming pools, and saunas.
Verification (Inspection and Testing): This section is crucial, detailing the required tests that must be performed to ensure the installation is safe before it is connected to the electricity supply.
It is important to note that AS/NZS 3000:2007 has been superseded by later editions, most notably AS/NZS 3000:2018. However, depending on local regulations in Australia and New Zealand, the 2007 edition (including its amendments) may still be cited in legislation and thus remain the standard to be followed for certain work.
