35 Test Switches Details & Test Switch Covers 5 TEST SWITCHES Switch Blades Two dimples coined into one side of the switch blade ensure positive contact in corrosive, sooty environments even after years of inactivity. Test Switch Covers Standard test switch covers are made from impact resistant clear thermal plastic which has excellent tracking and moisture resistant properties. If covers are required, add suffix -WC (with cover) to the catalog number or order separately catalog number K88. Black flush mount covers are also available. Order catalog number K88-BLK-FL. 0 pole base only. Standard Cover Test Switch Base The base is molded from a high strength, fiberglass reinforced, thermoset polyester. This material is track resistant, flame retardant and has low water absorption qualities. Bases are available in 7 pole and 0 pole sizes. Switch Jaws The switch blade jaw clips are constructed from spring grade copper alloy. The material and design ensure excellent contact which prevents overheating. Nickel Plating Option Corrosion-resistant test switches with nickel plating are available as an option. Socket shells must be 5 8" deep -ORmust not have test switch bridge mounted on back in order to support a cover. Polarity Barrier For maximum protection potential circuits are supplied with permanently mounted barriers made from high tensile strength polycarbonate. Current Carrying Parts Highly conductive copper and copper alloy materials are used on all current carrying parts. This ensures conductivity and deters corrosion. Spring grades are used where appropriate. Plating is available if required. Contact general offices to special order. Flush Mount Cover (Black) Factory Installed: For cover installed add the suffix -WC or -WCFL to the catalog number of desired test switch. Field Installed: For field installed cover order kit number K88 or K88-BLK-FL. The Milbank test switch is designed to meet the critical requirements of the electric utility industry. Not only do they meet EEI, ANSI C2.9, and UL standards but they combine several special features giving the Milbank test switch increased safety, durability and reliability. One such feature is our unique switch blade contact points which cut through residue that builds up after years of service. Another distinction is our polarity barrier which is designed to be flexible as well as offer exceptional insulating qualities. Our test switches are constructed from the latest materials available using modern fabricating and assembly methods. Milbank Manufacturing 480 Deramus Ave., Kansas City, MO milbankworks.com

Give equipment a thorough visual examination to determine that: ) No shipping or installation damage exists. 2) Proper clearances have been maintained. ) All connections have been made. 4) Equipment is clean and dry. B. Make a thorough examination to: ) Verify tightness of all bolted connections (see table below). 2) Manually operate all circuit breakers, switches, relays, etc. ) Check rigidity of all mountings, bus bars and components. 4) Use test equipment to check continuity of circuitry and integrity of insulation. C. All switches and circuit breakers should be in the off position. D. Verify that manual meter bypass (if applicable) is in non-bypass position. E. Install cover and/or close doors. F. If installation is not being energized at this time, follow after-energizing steps listed below. These steps will secure the installation in case of accidental energization. When Energizing A. Use caution and follow established safety procedures: ) Wear safety apparel. 2) Use safety equipment. ) Take action to prevent injury to yourself and others in the event of failure of the installation. 4) Take action to prevent/decrease damage to property in the event of failure of the installation. 5) If you are unsure how to safely energize the installation, get someone who is knowledgeable to do it. After Energizing A. Secure the installation: ) To prevent accidental contact with energized parts, cover all openings with approved filler devices. 2) To prevent unauthorized access, secure all covers and/or doors with approved security devices. ) Attach/post information to advise others of potential hazards associated with the installation.
