As3008 Current-carrying Capacity Table Jun 2026

(officially AS/NZS 3008.1.1:2017 – Electrical installations – Selection of cables – Cables for alternating voltages up to and including 0.6/1 kV ) is the Australian and New Zealand Standard that provides methods for determining the current-carrying capacity of cables. It is the essential reference for sizing copper and aluminum conductors in low-voltage installations.

| Conductor area (mm²) | Method A1 (Enclosed in conduit in insulated wall) | Method C (Clipped direct to surface) | Method D (Buried direct) | |----------------------|----------------------------------------------------|----------------------------------------|---------------------------| | 1.5 | 16 A | 21 A | 19 A | | 2.5 | 22 A | 29 A | 26 A | | 4 | 30 A | 39 A | 35 A | | 6 | 38 A | 50 A | 45 A | | 10 | 52 A | 68 A | 62 A | | 16 | 69 A | 91 A | 82 A | as3008 current-carrying capacity table
