Rule 49.1C
49.1-C. Setting of Wood Poles
The depths of pole settings are given in Table 6 are applicable to wood
poles set in firm soil or in solid rock. Where the soil is not firm
deeper settings or special methods of pole setting should be resorted to.
Where unguyed poles are set subject to heavy strains, or at corners or curves,
a greater depth should be used. Guyed poles may be set set not more
than one foot less than the depths specified in Table 6 provided the guys
do not assume any normal working load under conditions of no wind and the
resulting depths of settings are not less than 3 feet.
For communication lines, sawed poles of a cross section of 36 square inches
or less may not be set to a depth of 6 inches less than the specifications
shown in the following Table.
Metallic poles that are set directly in firm soil or rock shall be set at
least as deep as specified in Table 6 for wood poles. Where the resultant
bearing surface is not sufficient to prevent over- turning or excessive movement
of the pole at the ground line under maximum loading conditions, special measure
such as heel and toe bracing, setting in concrete, or bolting to a concrete
foundation shall be employed.
