AS/NZS 3008.1.1:2017
Table 30, 34, 35
Reactance at 50 Hz and a.c. resistance at 50 Hz
The voltage drop, voltage rise, loop impedance and cable size tools read this data on the AU 2017 edition. It gives resistance and reactance. The values print the same as the New Zealand part. The loop power budget reads the conductor resistance.
Verified: read against the printed standard, pages 98, 102–103. Checked 24 Sept 2026.
Units: R ohm/km, X ohm/km
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
