POLE SPECIFICATIONS:
Ground Pole "A"- 4.50 O.D. SCH 40 (4.026 I.D.) Steel - (Metric = 114.3 mm x 102.3 mm I.D.)
Ground Pole "B"- 4.50 O.D. SCH 80 (3.826 I.D.) Steel - (Metric = 114.3 mm x 97.2 mm I.D.)
NOTE:
1. Poles are not supplied (purchased locally to ASTM A501) and must be field drilled 5/8 diameter for M10 #3 rebar, drilled
5.55 mm (.218") for 1/4-20 self tapping grounding screw and galvanized or painted for protection.
2. Pole and foundation design based on the following criteria:
a. Uniform building code Exposure C and 1.5 stability factory.
b. Vertical soil pressure of 2000 pounds per square foot. (9765 Kilograms/meter square)
c. Lateral soil pressure of 300 pounds per square foot. (1465 Kilograms/meter square)
d. Concrete compressive strength of 2500 pounds per square inch (176 Kg/cm
CAUTION: The foundation design shown does not represent an appropriate design for any specific locality, since soil
conditions vary and may not meet design criteria given in Note 2. You should consult a local professional engineer to
determine your soil conditions and appropriate foundation.
