Current ratings, multicore cable with three or four cores, thermoplastic 75 °C

The cable size tool reads the printed rating here for a thermoplastic multicore cable, in copper or aluminium, for each installation method. That figure is the starting point, before any derating.

Verified: read against the printed standard, pages 62–64. Checked 24 Sept 2026.

Units: Rating A

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