Preparing the Site
Prepare the site for installation of a pre-cast pad. Some pads may require custom
preparations. Refer to the manufacturer's instructions for more information.
A general practice is described below for reference. Adapt the instructions as needed for local
requirements, practices, or conditions.
DANGER!
Do not place outside plant cables at the pad site before
installing the pre-cast pad. Attempting to install a pre-cast pad over existing
cables becomes hazardous if a person must reach underneath the lowered
pad to feed cables through its entry cutout.
To prepare the site for pad installation
1.
Excavate the pad area. Dig a foundation hole at least six inches deep with a perimeter
measuring at least 130 x 160 inches.
2.
Grade and compact the excavated surface until it is firm and level.
3.
Trench out conduit paths through the foundation hole (from the cable feeder location).
Refer to the pad drawings for conduit locations.
4.
Place the cable conduits into the conduit trench. Refer to the pad construction guidelines
for conduit sizes and locations.
5.
Route the earth ground wires through the conduit trench (from the ground electrode).
6.
Place gravel into the foundation hole to create a level base. The gravel layer should be at
least two inches deep, compacted and leveled.
