Table C8
Simplified voltage drop, ampere metres per percent
The simplified selector reads the ampere metres per percent of voltage drop that Table C8 gives. It reads them for each conductor size, for one phase and for three. The table stops at 95 mm², and the tool says so rather than extrapolating.
Verified: read against the printed standard, pages 481. Checked 26 Sept 2026.
Units: Size mm2, Am per percent A*m per %
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
