Refer to Table 3-3 for the recommended foundation size. Figure
3-2 and the following information provide the installation
information.
These recommendations are based on the soil
conditions listed and do not consider any special clearance
requirements.
The minimum safe soil-bearing capacity is 2000 PSF (96 kN/m 2 ).
1.
2.
Reinforcing bars shall conform to ASTM A615, grade 60.
3.
Do not weld anchor bolts to reinforcing bars. This will remove the
temper and reduce the strength of the anchor bolts.
4.
All concrete shall be building code standard weight 3000 psi (20,700
kN/m 2 ) compressive strength at 28 days.
5.
Areas (6 X 12 inch or 15.2 cm X 30.4 cm) for mounting feet should
be flat within 1/16 inch and level with respect to one another within
1/4 inch (6 mm).
6.
Anchor bolts are 1 inch diameter and must conform to ASTM A193
grade B7 or ASTM A325.
7.
Do not use nuts under the foot, 454063. The foot must rest flush on
the concrete pad. Use one washer, 85844, and one flourocarbon-
coated nut, 337880, per anchor bolt to secure foot to pad. After the
concrete is fully cured, torque the nuts to 245-270 foot-pounds (333-
367 Nm).
Refer to Figure 3-3 for 6-meter 120° conduit placement.
