1. The switchgear shall be S&C Model 633, Catalog #936332R1-F2-L2-O-T3-M3-P94P197, and shall conform to the following specification. 2. The switchgear shall consist of a gas-tight tank containing SF6 gas, load-interrupter switches and resettable fault interrupters with visible open gaps and integral visible grounds, and a microprocessor-based overcurrent control. Load-interrupter switch terminals shall be equipped with bushings rated 600 amperes continuous, and fault-interrupter terminals shall be equipped with bushing wells rated 600 amperes continuous to provide for elbow connection. Manual operating mechanisms and viewing windows shall be located on the opposite side of the tank from the bushings and bushing wells, so that operating personnel shall not be required to perform any routine operations in close proximity to high-voltage elbows and cables. Using gas-tight air-insulated bushings on one or both sides of the tank, multiple tanks shall be joined together, as required, with air-insulated transition bays.
