Electrical installations (known as the Australian/New Zealand Wiring Rules)

Included in Electrical installation set

AS NZS 3000 2018 (known as the Australian/New Zealand Wiring Rules) specifies requirements for the design, construction and verification of electrical installations, including the selection and installation of electrical equipment forming part of such electrical installations. Part 1 provides provisions that constitute the minimum regulatory requirements for a safe electrical installation. Part 2 provides work methods and installation practices that are ‘deemed to comply’ with the requirements of Part 1.
