Cable Current Ratings — AS/NZS 3008
Free download · 85 × 54mm (credit card size)
This credit-card-sized reference card puts the most-used cable current ratings from AS/NZS 3008.1.1:2017 in your pocket. The front face shows Cu/XLPE 90°C current ratings for 8 common cable sizes (1.5mm² to 240mm²) across three installation methods — enclosed in conduit, on perforated tray, and direct buried — sourced directly from Table 13 and Table 14. Flip it over and you get the essential derating factors: ambient temperature correction from Table 22, grouping factors from Table 25, and soil thermal resistivity corrections from Table 27. A QR code on the back links directly to our full cable sizing calculator for when you need precise results beyond quick reference. Designed for Australian and New Zealand electrical engineers, contractors, and apprentices who need instant access to cable data on site without pulling out a full copy of the standard.
