AS/NZS 3008.1.1:2025
Table 4.1(A), 4.1(B), 4.5(A), 4.5(B)
Reactance at 50 Hz and a.c. resistance at 50 Hz
On the 2025 edition, the voltage drop, voltage rise, loop impedance and cable size tools read resistance and reactance here. The values print the same as in 2017. The loop power budget reads the conductor resistance.
Verified: read against the printed standard, pages 96–97, 102–103. Checked 27 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.
