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.
