Cable Vault and Pad Installation

Hubbell Cable Vault and Pad can be easily installed by following these simple guidelines:

Note : Before beginning excavation work, investigate the possibility of other buried utility lines or enclosures. Hubbell vaults are normally shipped assembled and complete. These are equipped with studs near each corner where a lifting sling can be attached for handling with suitable lifting equipment. Excavating equipment is required, as is equipment or tools to lift and place the vault into the excavated area. Hand tools that may be required to assemble the enclosure include: hammer and/or mallet, hex-socket (3/4-in.), rasp or coarse file pliers, band cutter or shears and penta-socket wrench. Workers handling the enclosure during installation should wear work gloves to prevent injury. For new work, excavate approximately 10 inches around the outer width of the vault being installed and 6 inches deeper than actual depth of the vault. 1. For new work, excavate approximately 10 inches around the outer width of the vault being installed, and 6 inches deeper than actual depth of the vault. 2. Place six inches of free-draining granular fill in the bottom of the excavation and level it. Grade the granular fill so that the top of the vault will be at the correct final grade. 3. Remove the bolts holding the pad onto the vault. Remove the pad and set it aside. Place the vault into the excavated area. Adjust fill as required to obtain correct line and grade for the top of the box. 4. Install a temporary 2x4 brace across the vault each way at the midpoints of the upper pad-supporting ring prior to backfilling. 5. Begin placing and compacting fill around the enclosure per specifications or instructions.

Hill Holders Installation

Hubbell Hill Holders can be easily installed by following these simple guidelines:

1. Prepare a level base area

approximately 3 inches below the finished grade. Set the Hill Holder in position and install 3 inches of crushed rock inside the Hill Holder. 2. Set the pad and transformer in place. 3. Complete by backfilling behind the Hill Holder. Re-install the equipment pads and bolt them securely into place.

The pad is now ready for equipment installation.
