Three load types should be considered: static weight loading, ice loading, and wind loading. These types should be considered on the pole, wires, and any equipment installed on the pole. A qualified engineer should perform the pole loading analysis, taking into account both vertical and horizontal forces. The specified horizontal load is applied 2 ft. (60.1 cm) from the top and the assumption is that the pole acts as a cantilever with maximum stresses applied at the ground level. Table 20 provides acceptable loads by pole class.

The strength of the wood pole is defined in Standard Handbook for Electrical Engineers, 13th Edition, McGraw Hill, Chapter 18, Section 135, “Strength of Wood Poles,” Pages
The Digivance NXD Wood Pole Mounting Bracket, shown in Figure 26, is an accessory item that is used to attach the Digivance NXD cabinet to a power distribution pole or related object. The bracket is attached to the pole using galvanized steel square head bolts that are attached through holes drilled through the wooden pole. An example of an installed NXD wood pole mounting bracket is shown in Figure 26.
Use the following procedure to install the RAN wood pole mounting bracket:
1.Determine the mounting height of the RAN and mark the pole at the desired location of the base of the RAN.
Note: Install the RAN pole mount bracket on the side of the utility pole assigned by the utility company or required by local zoning.
