Installing a Pre-Cast Concrete Pad
A concrete pad provides a permanent foundation to anchor the cabinet to the ground while protecting the cabinet from water
damage and other outdoor surface conditions.
Install a pre-cast concrete pad for the cabinet at the installation site. Installation requires excavating the site, trenching cable
conduit, creating a gravel foundation base, and installing the pre-cast pad.
Pre-cast pads typically ship configured with conduit entry cutouts and mounting fixtures (anchor studs or countersunk
threaded inserts) for anchoring the cabinet to the pad. Specific features and dimensions vary by manufacturer. Contact your
sales representative for a list of Clearfield -certified suppliers to contact directly.
Preparing the Site
Prepare the site for installation of a pre-cast pad according to the manufacturer's instructions. Some pads may require
custom preparations.
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 into conduits 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 a lowered pad to feed cables through its entry cutout.
Excavate the pad area. Dig a foundation hole six inches deep with a perimeter measuring at least 48 x 72 inch-
es; dimensions may vary based on manufacturing requirements and the selected FAC 900 configuration.
Grade and compact the excavated surface until it is firm and level.
Trench out conduit paths through the foundation hole from the cable feeder location.
Place the cable conduits into the conduit trench.
Route the earth ground wire through the conduit trench (from the ground electrode).
Place gravel into the foundation hole to create a level base. The gravel layer should be at least two inches
deep, compacted and leveled.
Note:
When installed, the pad should stand at least one inch above grade. Adjust the compaction and gravel
depth accordingly, based on the pad height.
