Table 3.19

Current ratings, multicore cable with three or four cores, cross-linked 90 °C

On the 2025 edition, the cable size tool reads this table for a cross-linked multicore cable. It gives the printed rating in copper or aluminium for each installation method. The buried-direct ratings up to 10 mm² differ from 2017.

Verified: read against the printed standard, pages 50–51. Checked 27 Sept 2026.

Units: Rating A

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