for MlO #3 rebar, 5.5 mm for self tapping grounding screw and (.218") for 1/4-20 self tapping grounding screw. Poles and screws must
be galvanized or painted for protection .
2. Pole and foundation design based on the following criteria:
.c.
Uniform building code Exposure B or C wind loading .
b. Vertical soil pressure of 13790 kPa (2000 pounds per square foot).
c. Lateral soil pressure of 2758 kPa (400 pounds per square foot).
d. Concrete compressive strength of 17.2 MPa (2500 pounds per square inch) in 28 days.
3. See page 6 for grounding recommendations.
CAUTION: The foundation design shown does not represent an appropriate design for any specific locality. Soil conditions vary and may
not meet design criteria given in Note 2. Consult a local professional engineer to determine your soil conditions and appropriate foundation .
