Cl 3.9.8
Segregation and separation of wiring systems
The segregation tool reads one row per case: what may share a pipe or cable, what needs segregation in a common enclosure, which voltage levels may mix, and the separation from gas, water and telecommunications services.
Verified: read against the printed standard, pages 181–184. Checked 27 Sept 2026.
Units: Separation mm mm
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
