Box Pads and Ground Sleeves Installation

Hubbell Box Pads and Ground Sleeves can be easily installed by following these simple guidelines:

1. Determine the cable or conduit entry position and then excavate a hole for the base. 2. Make the hole 1 to 2 feet longer and wider than the base and approximately 8 inches deeper. 3. Put eyebolts into lifting inserts on top of the base. (Four bolts are shipped with the foundation base.) Attach lifting chain or straps to the bolts. Once chain or straps are attached, lift and position the base into the hole using a backhoe or other equipment. Insure orientation of box pad or ground sleeve meets the plan. 4. Place gravel in the base to a depth of approximately 6 to 8 inches. Lift base to proper elevation, allowing gravel to run out under the base. Check the elevation of the base, make the necessary elevation adjustments with the bucket and then recheck the elevation. 5. Once the base is set to proper elevation, remove the bolts and place backfill around the box pad using normal utility practices for backfilling. If compaction is required, internal bracing (see page 134) must be used enclosures to prevent deflection and premature failure.

Equipment Support Pads Installation

Follow these simple guidelines to install Hubbell Support Pads:

1. Determine the cable or conduit entry position and then dig a recess so the top surface of the pad will be level with the surrounding area. 2. Level the dirt around cable opening and then level and tamp down dirt in the area to be occupied by the foundation pad. 3. Backfill and tamp in trench area leading to cable opening. Place pad in a prepared, level area with opening in pad (throat) directly over cable entry position. 4. Attach equipment to the foundation pad with bolts, brackets and/or lugs provided by the equipment manufacturer. Backfill and tamp earth around the pad so it is level with surrounding landscape.
