Concrete Foundation Pad
CAUTION!
The compression strength of the concrete pad used must be a minimum of 4000 psi as determined by ASTM
C39 test of compression strength of concrete cylinders.
The enclosure is installed on a concrete foundation pad, which is either cast-in-place or precast. Figure 6.2 shows the general position
of the enclosure on the concrete pad.
•
Use concrete only for the foundation pad. Do not use substitute materials, such as reinforced plastics, since they lack the
rigidity required for enclosure placement. The ideal pad dimension extends two feet beyond the open radius of all doors.
The minimum recommended pad size is two feet (24 in or 60.96 cm) beyond the perimeter of the enclosure.
•
If not using a metal mounting template, use the mylar-type reusable film template (P/N F1010584 [145344]) or the
dimensions in Figure 2.7 to orient the mounting bolt holes and conduit openings in the pad. The metal mounting template
(P/N F1010585 [554917]) consists of galvanized metal mounting plates with support rails. A rubber barrier pad is installed
between the pad and the enclosure to prevent corrosion.
•
For excavated pad applications, excavate a hole for the pad and cable conduits in accordance with the engineering work
prints, generally to a depth of 30" (76.20 cm) for standard applications and 60" (115.24 cm) for areas where there is heavy
frost.
•
Use a minimum of 6" (15.24 cm) of sand or gravel as a base for the foundation pad. This will level the location to accept the
pad.
•
Use a high-early strength concrete mix so the enclosure may be placed three days following concrete pouring. Coarse
aggregate used in the concrete shall be graded from 3/4-in (1.90 cm) to No. 4 only.
NOTE!
Referring to Figure 6.2, determine the proper pad size for your application and space available. The MINIMUM
recommend pad size extends 24" (60.96 cm) past all sides of the enclosure. If space permits and it is desired, a larger pad
can be constructed thus providing area to walk around the installed enclosure. Refer to Figure 2.2 and Figure 2.3 for
enclosure dimensions.
NOTE!
Referring to Figure 2.5, note conduit and mounting locations. Note that conduits may also be run to the rear lower
access panel.
Optional Pour-in-Place Pad Template: Referring to Figure 2.8, note conduit and mounting locations for the pour-in-place
template assembly.
NOTE!
Referring to Figure 6.3 or Figure 6.4, prepare a form per “Form Preparation” on page 31. Follow local practices or
building codes if different than the information included in this section.
