Resources

Quick-reference lookups and cheat sheets for the Australian and New Zealand electrical standards, built to sit alongside the calculators.

The 2025 edition of AS/NZS 3008.1.1 renumbered many of its tables, so a calculation sheet, textbook or old job file that quotes a 2017 table number points at the wrong table in the current book. The table map below lists each commonly used table in both editions, grouped the way you work through a cable selection: current-carrying capacity, derating, then voltage drop. These resources point you to the right place in your own copy of the standard; they do not reproduce its tables.

AS/NZS 3008.1.1

AS/NZS 3008 table numbers: 2017 to 2025

Lookup mapping every commonly-used AS/NZS 3008.1.1 table number from the 2017 edition to its 2025 equivalent, current-carrying capacity, derating factors, and voltage drop.
