Wiring Methods for Secondary Distribution Boxes in Australia
AS/NZS 3000 Section 5 sets the rules for the Multiple Earthed Neutral (MEN) system used across Australia and New Zealand, the sizing of the main earthing conductor, and equipotential bonding of metallic services and structural steel. Universally called the Wiring Rules, it governs every electrical installation from the point of supply (typically the main switch) through to the final socket outlet, fixed equipment, and connected luminaire. This design standard for Secondary Systems outlines the minimum protection, electrical, automation, and communication design required for deployment of secondary systems into TransGrid's network. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. This Joint Australian/New Zealand Standard was prepared by Joint Technical Committee EL-001, Wiring Rules.
