  • Patent number: 6177630
    Abstract: An electrical and electronic equipment installation pad includes a precast concrete support slab 40 having an electrically conductive pathway disposed therein. The pathway may be comprised of a plurality of steel reinforcing rods 42 welded to one another to form a grid 44. Coil loop inserts 46 disposed within the slab 40 and welded to the grid 44 receive electrically conductive bolts for securing the equipment 20 on the slab 40. Galvanized inserts 48, 50 having bolts 52, 54 extending therefrom are also disposed within the slab 40 and welded to the grid 44. Ground rod leads 34 from ground rods 36 installed in the ground proximate to the pad 10 are connected to the galvanized inserts 48, 50 providing a path for fault currents from the equipment 20 through the grid 44 to ground. The pad 10 may be used to install equipment 20 at a desired location by first securing the equipment 20 on the pad 10 while the pad 10 is at a location remote from the desired location and then moving the pad 10 to the desired location.
