GENERAL NOlES: <br />An existing external buried ground ring should be found around the perimeter of the existing equipment shelter and/ or tower <br />foundation. A lead shall be run from the generator base to the existing ground ring. <br />An external buried ground ring shall be established around the generator and The ground ring shall be kept 24" from <br />foundations <br />The buried external ground ring shall consist of #2 solid bore tinned copper conductors. A minimum bend radius of 12 <br />inches shall be maintained. Connections from the ground ring conductors to the ground rods shall be made by exothermic <br />welds, brazed welds, or gas tight listed compression connectors pre filled with antioxidant compound. <br />Ground rods shall be galvanized stee~ 10'-o" by 5/8"0, spaced 8'-0" to 15'-0" apart. Rod tops shall be driven to a depth <br />of 6" below frost level. Rods and ring shall be kept 24 inches from foundations. <br />All below grade connections shall be joined by exothermic welds or by gas tight UU67 fisted compression connectors. <br />Connections shall Dai be coated with cold galvanizing compound. <br />All connecting lugs shall hove two hole tongues. Lugs joined to solid conductors shall be joined by exothermic or brazed <br />welds or shall be UL listed, 10,000 PSI, irreversible long barrel compression lugs or RECOGNIZED two hole screw on ring <br />terminal. All lug connections and their mating surfaces must be cleaned to shiny metal and lightly coated with a non oxidizing <br />type conductive grease or compound. <br />All exothermic connections to galvanized materials shall hove the galvanizing ground off prior to making the connection. After <br />the connection has been made, the joint shall be re-coated with a cold galvanizing compound. <br />#2 Solid Bare Tinned Copper Lead. <br />Leads from the generator frame sholl connect to the generator ground ring by one exothermic weld or by gos tight UL 467. <br />fisted compression connectors. <br />Leads from generator ground ring shall connect to the exisitng external round ring by one exothermic weld or by gas tight <br />UU67 listed compression connectors <br />Each vertical support pipe of the exterior generator ice shield bridge. The ice shield grating shall be jumpered to the vertical <br />support pipes with #2 Solid Bare Tinned Copper at each vertical support pipe. Each ice shield grating shall be jumpered to <br />each other with #2 Solid Bore Tinned Copper. <br />NEW GROUNDING SHALL BE BONDED TO EXISTING LE"AD 1 lHAT IS FOUND AROUND EXISTING EQUIPMENT SHELTER OR TOWER.
