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 and, prestressed concrete poles, or poles of other non-wood materials 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 of these poles 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, or other special methods shall be used.
