The rods must be centrally positioned inside the well.

f. Ground rods must be orientated vertically except if prohibited by earthen obstructions, in which case they must not exceed 45 degrees from the vertical. position Install the ground rods using appropriate ground rod drivers without breaking or deforming the rods.

g. Install ground rods in 6 inch wide ground access wells made of High-Density Polyethylene (HDPE) or schedule 80 PVC with a cap made for the purpose of inspecting ground rods.

i. This well should have adequate drainage to prevent water from infiltrating.

h. Ground access wells will be flush with stone.

2. The ground conductor/wire must be #2 AWG stranded copper wire and must be connected to the ground rods by exothermic weld.

Route conductor in schedule 80 pvc conduit sized per NFPA 70 for the total length of outdoor run to the door on level two all other areas inside the dam the ground conductor is to be ran, open air installation is sufficient.

4. Install the ground conductor in one continuous, straight length without splices or joints. When necessary, bends at locations including but not limited to the corner of the walls, and top and bottom of the elevator shaft must be made in such a way to avoid damage to the conductor.

5. Secure the conductor wire against the wall using proper size EPDM cushion clamps or equivalent with stainless steel fasteners. The conductor must be secured in accordance with NEC specifications.

6. Route the ground conductor through the wall next to training wall door and then route the copper wire down and below the platform and along the second lift joint from the ground into the location of the ground rods.

This ground conductor should be installed in the Monolith joints during vertical transitions and lift joints during horizontal transitions. See Attachment #10 – Ground rods and Wire run.

7. Ground conductor must be routed inside concrete lift joint cavity in the wall to reduce shearing of conductor by falling rock and/or ice.

8. Clean the entire surface of ground busbar and drill the holes into the ground busbar prior to making connections to the bare copper wire. The bare copper wire and ground busbar connections must be made by using tin-plated copper or copper-alloy bolts and nuts.
