SUMMARY This Section specifies the requirements for disconnect switches and fusible switches only. REFERENCE STANDARDS The latest published edition of a reference shall be applicable to this Project unless identified by a specific edition date. All reference amendments adopted prior to the effective date of this Contract shall be applicable to this Project. All materials, installation and workmanship shall comply with the applicable requirements and standards addressed within the following references: Federal Spec. W-S-865 - Switch, Box (Enclosed), Surface Mounted. NEMA KS 1 - Enclosed Switches. ANSI/UL 98 - Enclosed and Dead-Front Switches. NFPA 70 - National Electrical Code (NEC). NFPA 70E - Standard for Electrical Safety in the Workplace. SUBMITTALS Submit manufacturers product data, including: 1. Ratings including voltage, and horsepower or continuous current. 2. Dimensioned outline drawings. 3. Conduit entry/exit locations. 4. Cable terminal sizes. 5. Wiring diagrams. Submit dimensioned Shop Drawings and equipment ratings for voltage, capacity, horsepower, and short circuit. DELIVERY, STORAGE and HANDLING Deliver switches individually wrapped in factory-fabricated water-resistant type containers. Handle switches carefully to avoid damage to material components, enclosure and finish. Store switches in a clean, dry space protected from weather. PRODUCTS GENERAL All materials shall meet or exceed all applicable referenced standards, federal, state and local requirements, and conform to codes and ordinances of authorities having jurisdiction. MANUFACTURERS ABB/General Electric Company. Square D Company. Eaton. Siemens. CONSTRUCTION Enclosure. Provide NEMA 1 enclosures for switches in indoor dry locations. Provide NEMA 4X enclosures for switches located outside the building conditioned envelope. Provide NEMA 4X stainless steel enclosures for switches located in outdoor environments, unless otherwise shown. Operating Handle. Provide a handle suitable for padlocking in the OFF position with as many as three padlocks of 5/16-inch diameter shank. Use a defeatable, front accessible, coin-proof door interlock to prevent opening the door when the switch is in the ON position and to prevent turning the switch ON when the door is open. Terminal Shield. Provide incoming line terminals with an insulated shield so that no live parts are exposed when the door is open. Neutral. Provide each switch with an isolated, fully rated neutral block. Make provisions for bonding the block to the enclosure. Ground. Provide each switch with a ground lug. Fuse Holders. Provide switches with rejection-type fuse holders which are suitable for use with fuses specified under Section 26 28 13, Fuses - 600 Volt and Below. All switches shall be fused. Nameplates. Provide metal nameplates, front cover mounted, which indicate the switch type, catalog number and horsepower rating (with both standard and time delay fuses). FABRICATED SWITCHES Depending upon the service indicated, use 250- or 600-volt switches, single throw, fusible, or non-fusible, horsepower rated, heavy duty, designed for locking in ON or OFF position, in code-gage steel cabinets. Use switches which have number of poles required, dependent upon phase serving equipment. Switches shall be NEMA 1 Underwriters approved for duty shown. In wet locations, use NEMA 3R. Where exposed to weather in exterior applications, use NEMA Krylon, corrosion resistant type. NEMA 3R and NEMA Krylon switches shall have weatherproof threaded hubs for all conduit entries into switch. Use fuse clips that are rejecting type to accept Class RK or L fuses. Refer to Section 26 01 00 for nameplate information. EXECUTION INSTALLATION Installation shall meet or exceed all applicable federal, state and local requirements, referenced standards and conform to codes and ordinances of authorities having jurisdiction. All installation shall be in accordance with manufacturers published recommendations. Install safety or disconnect switches for all electrical equipment, in accordance with the applicable requirements of NEC and the National Electrical Contractors Association Standard of Installation. For all equipment with motors larger than 1/8 horsepower, provide motor rated disconnect switches within sight of the motor. Disconnect switches for such equipment shall be mounted independent of the unit to allow for maintenance access. FUSIBLE DISCONNECT SWITCHES Provide fusible disconnect switches only. Coordinate with Divisions 14, 21, 22, 23, and equipment supplier for warranty and listing requirements of equipment approved by submittal. Coordinate fuse selection with the overcurrent protective device coordination study. Refer to Sections 26 05 73 and 26 28 13. Install fuses in fusible disconnect switches. Provide permanent marking inside switch enclosure for fuse type and size.
