This section covers the furnishing and installation of grounding materials, 4C.2 MATERIALS. All grounding materials required shall be furnished new and undamaged in accordance with the following requirements: Rods 3/4 inch 10 foot copperclad sectional type Copperweld, Blackburn or approved equal Cable Bare Soft drawn copper, Class B stranding, ASTM B3 Insulated Soft drawn copper, Class B stranding with not less than 3/64 inch thick green colored polyvinyl chloride insulation IPCEA S-19-81 Bus and bars Soft copper, cross section not less than 1/8 inch thick by one inch wide, ASTM B187 Thermite we'.ds Molds, cartridges, materials, and accessories as recommended by the manufacturer of the molds for the • items to be welded. Cadweld heavy- duty or approved equal. Molds and powder shall be furnished by the same manufacturer Flush ground plates Cadweld S-3301 M-2745, s-3688 or approved equal All clamps and other hardware of iron or steel used with the grounding system shall be hot-dip galvanized. Bolts, washers, and nuts shall be cadmium plated, 4C.3 INSTALLATION. Grounding system materials shall be installed ac- cording to the drawings and following requirements. (DENTON, TE?(AS - 4904 ) (SUBSTATION CONSTRUCTION - D-2) 4c-1 110570 4C.3.1 Ground Grid. Ground grid conductors under buildings or struc- tures shall be buried with at least 6 inches of earth cover. Buried grounding conductors extending beyond the foundations of buildings or structures shall have at least 18 inches of earth cover. 4C.3.2 Ground Rods. All ground rods shall be located as shown on the drawings and driven to the depth indicated. Where the required ground rod length exceeds 10 feet, standard sections shall be welded together to provide an extended rod with one true centerline and a minimum of joint resistance. 4C.3.3 Conductors. Exposed conductors shall be installed inconspicu- ously in vertical or horizontal positions on supporting structures. When located on irregular supporting surfaces or equipment the conductors shall run parallel to or normal to dominant surfaces. Conductors routed over concrete, steel, or equipment surfaces shall be kept in close contact with those surfaces by using fasteners located at intervals not to exceed 3 feet. Damaged ground system conductors s'iall be repaired or replaced by the Contractor as directed by the Engineer. 4C.3.4 Connections. All connections shall be made by the thermite process except where otherwise shown on the plans or specified. Manu- facturer's instructions on the use of thermite materials shall be fol- lowed in all details. All surfaces to be covered by the thermite welds shall be thoroughly cleaned. Paint, scale, and other deleterious sub- stances shall be removed from surfaces of ungalvanized structural steel members by grinding. Galvanized steel surfaces shall be cleaned with emery paper. Powder and molds shall be kept dry and warm until used. All thermite connections shall successfully risist moderate hammer blows. Any connection which fails such test or which upon inspection indicates a porous or deformed weld shall be remade. Where flush ground plates are to be embedded in the concrete, the plates shall be carefully located and firmly secured to the forms. The ground- ing cable shall be thermite welded to the plate. All bolted and screwed connections shall be securely tighten^d. 4C.3.5 Conduit Grounding. All grounding bushings within all enclosures, including equipment enclosures, shall be wired together and connected internally to the enclosure grounding lug or grounding bus with bare copper conductor. Grounding bushings 1-1/2 inches and smaller shall be grounded -with 8 AWG conductors. Grounding conductors sized in accordance with NEC shall be used with all other grounding bushings. (DENTON. TEY.AS - 4904 ) (SUBSTATION CONSTRUCTION - D-2) 4C-2 , 100170 Where conduit runs are terminated at tray and the conduit carries a separate grounding conductor the ground conductor in the conduit run shall be continued through the conduit bushing ground connection and terminated on the tray grounding cable. Grounding. A bare grounding conductor shall be installed 4C. 3.6 T La the entire length of cable trays where indicated on the drawings. The conductor shall be connected to each tray section and the tray ground system connected to the station grounding grid as shown on the drawings. 4C.3.7 Equipment Grounding. All electrical equipment shall be grounded. Large equipment such as metal-clad or metal-enclosed switchgear will be furnished with a grounding bus. Most other equipment will be furnished with grounding pads and/or grounding lugs. All ground connections shall be cleaned immediately prior to connection. The Contractor shall provide all grounding material required but not furnished with the equipment. The conduit system is not considered to be a grounding conductor except for lighting fixtures. No grounding conductor shall be smaller in size than 12 AWG unless it is a part of an approved cable assembly. 4C.4 GROUND SYSTEM RESISTANCE. All ground resistance measurements shall be made with a three terminal "megger" type ground tester which applies alternating current to the electrodes and which gives a reading in direct current ohms. Two reference grounds shall be used and all tests shall be made in accordance with instrument manufacturer's instruc- tions for ground resistance testing. Prior to connection of grounding electrodes to the grounding system the Contractor shall obtain individual measured ground resistance data for selected electrodes as shown on the drawings. These data shall be ob- tained, identified, and recorded under the supervision of the Owner and sent to him within 5 days. The Contractor shall furnish, install, and connect grounding electrodes as the Owner may direct. Extra work required rcr electrode unit will be reimbursed the Contractor according to t*e unit price quoted in the Proposal. (Dumx, TExAs - 4904 ) 4C-3 (SUBSTATION CONSTRUCTION - D-2) 100170
