Table 26: Replacement Ground Line Circumferences In Inches
of Sound Solid Wood For Communication Poles in Grade “F” Construction
This table is suitable for poles supporting cables; interexchange
lines (toll trunk and telegraph way wire); and exchange or local distribution
lines of more than 10 wires. The circumferences given in this table are based
on a safety factor of one–half, a modulus of rupture in bending of 5,600
pounds per square inch, and the maximum number of wires (0.104” in diameter)
shown in the headings of the respective columns.
