Table 3.8, 3.10
Aerial conductor clearances and spacing at supports
The aerial spans tool reads the minimum clearance for each conductor type from Table 3.8. From Table 3.10 it reads the conductor spacing at the supports for a span. Table 3.10 stops at a 60 m span. The tool refuses a longer span rather than hold the 60 m figure.
Verified: read against the printed standard, pages 206, 208. Checked 26 Sept 2026.
Units: Clearance m, Spacing m, Span m
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
