833.1Description.
This work consists of providing and placing electrical grounding equipment.
833.2Materials.
833.3Construction.
Provide certified test reports verifying the ground resistance of each ground or ground grid when installed. 833.3.1 Ground Rods.
undisturbed soil at the locations indicated in the contract. Measure the ground resistance of each rod before connecting the rod to the grounding conductor. Ensure that, if the measured resistance exceeds 25 -ohms, in accordance with the National Electric Code, exothermically weld a 10 -foot extension to the top of the first rod and drive to its full depth. Measure the earth resistance again. Contact the engineer for d irection if the measured resistance still exceeds 25 - ohms. Exothermically weld the ground rod and joining ground wire after successful testing. Paint the weld and exposed cable with 2 coats of insulating varnish.
contractor cannot achieve an acceptable earth ground by driving as described above. Exothermically weld direct buried rods end -to-end to bond lighting standards and s tructures in a continuous series to a point where the contractor can obtain an acceptable ground.
connections to equipment grounding systems using suitable lugs at all grounding bushings specified, and at the ground lugs in lighting or traffic signal structure access holes or in a breakaway base. Make connections to ground rods in accordance with the contract. Make connections to neutral grounding systems using grounding lugs. 833.3.2 Bonding and Grounding Junction Well. Drill holes in the junction well cover and the junction well frame. Attach a braided bonding strap to both the cover and frame in accordance with the contract to ensure proper bonding. Bond the junction well frame to the existing ground wire in the junctio n well, using a compression connector such as a C-tap.
