E. GROUNDING CONNECTIONSFTWIC-2235June 20091. Provide exothermic connections equal to Cadweld. To substitute anotherexothermic weld process, the Contractor must submit a chemical analysis by anindependent testing lab certifying:a) Starting material, if used, contains no phosphorous, caustic, toxic, orexplosive substance.b) Weld metal used for grounding connections contains copper oxide,aluminum, and not less than 3% tin as a wetting agent. Weld metal forcathodic connections shall contain vanadium, but no tin.c) A minimum of 80 per cent of the weld metal shall screen out between 30and 140 mesh.2. The exothermic welding system furnished under these specifications shall meetthe applicable requirements of IEEE-80, Chapter 9, Section of conductors andjoints.3. Two styles of exothermic connections shall be available: One primarily forindoor and the other for outdoor application.a) Exothermic connections to be used outdoors shall be suitable forexposure to the elements or direct burial without degradation over thelifetime of the grounding system.b) Exothermic connections to be made in finished buildings or confinedspaces shall use the double filtered, low smoke, low emission, processwhich is metallurgically equal to the above connection.4. Molds shall be made from graphite or other material withstanding weldingtemperatures and shall be designed to provide an average life of not less than 50exothermic welds under normal conditions. The molds shall bear permanentmarking, indicating the name of the manufacturer, the mold model, the type andsize of welding mixture compatible with the welding process, and the size of theconductor. Instructions detailing general safety information, and weldingprocedures shall be provided with each mold. The installer is prohibited fromusing a mold from one manufacturer with a different manufacturer's weldingmixture.PART 3.00EXECUTION3.01 INSTALLATION:A. Insulate connections made with non-insulated connectors with a minimum of three layersof plastic tape. Half-lap each layer.B. Splice 600 Volt conductors in junction boxes or at outlets only. All splices, includingthose made with insulated wire nuts, shall be insulated with electrical tape or heat-shrinktubing to a level equal to the 600 volt rating of the factory insulated conductors. Allelectrical connections utilizing lugs with threaded set screws and wire sizes of 1/0 AWGand larger shall have an oxide inhibitor applied to prevent oxidation.16122-2
