As Nzs 3008 -

1. Executive Summary AS/NZS 3008 is the fundamental standard for determining the current-carrying capacity (ampacity) and voltage drop of copper and aluminium cables in Australia and New Zealand. It provides the engineering methodology to ensure cables operate within safe thermal limits, deliver adequate voltage to equipment, and comply with the wiring rules (AS/NZS 3000). This report outlines its structure, key principles, application methods, and critical parameters. 2. Scope and Structure The standard applies to low voltage (LV) installations up to 0.6/1 kV, and also provides methods for voltages up to 33 kV.
