Table 4.16, 4.18, 4.21, 4.23

d.c. voltage drop (mV/A.m) at the maximum conductor temperature

The DC cable size tool reads the d.c. mV/A.m of each size here. It multiplies that figure by the current and the route length.

Verified: read against the printed standard, pages 123, 126, 131, 134. Checked 27 Sept 2026.

Units: Mv per am mV/A.m

These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
