* Average outside diameter observed commercially.
** Minimum ultimate strengths of ASTM Specifications, B
1 - 39.
*** For stranded conductors, 90% minimum ultimate strength
of ASTM Specifications, B 2 - 39, plus 1/4 of the difference between maximum
and 90% of minimum ASTM values; for solid conductors, minimum ultimate strengths
of ASTM Specifications, B 2 39, plus 1/4 of the difference between minimum
and maximum.
