DONNELLY ENGINEERING ELECTRICAL <br /> SECTION 16490 <br /> AUTOMATIC TRANSFER SWITCH <br /> PART 1 -GENERAL <br /> 1.1 RELATED DOCUMENTS <br /> A. General: Drawings and General Provisions of the Contract, including General and <br /> Supplementary Conditions and Division 1 Specification sections,apply to work of this section. <br /> 1.2 DESCRIPTION <br /> A. General: Provide a automatic transfer switch of the size, number of poles,amperage,voltage <br /> and withstand ratings as shown on the contract drawings and as specified herein. <br /> B. Description: The switch shall automatically transfer the load to the generator during normal <br /> power outages after the standby generator timing period has elapsed. The switch shall be <br /> fully rated, electrically operated, mechanically held unit with both electrical and mechanical <br /> interlocks to prevent simultaneous energizing of both sides. The switch shall be housed in a <br /> NEMA 1 housing unless specified with a NEMA 3R listing. The switch shall be open and <br /> inspectable. <br /> 1.3 QUALITY ASSURANCE <br /> A. Manufacturer Requirements: Firms regularly engaged in manufacture of automatic transfer <br /> switches, of types and ratings required, whose products have been in satisfactory use in <br /> similar service for not less than 5 years. <br /> B. Manufacturers: Subject to compliance with the requirements of this specification,provide an <br /> automatic transfer switch manufactured by KOHLER, provide KTSDCTA 1600 Amp for <br /> equipment emergency. The transfer switch shall be as shown on the drawings. All contacts <br /> must be open and inspectable type. <br /> C. Standards: Comply With The Following Standards: <br /> 1. UL-1008 and UL 2200 <br /> a. As a precondition for acceptance, the transfer switch, complete with timers <br /> relays and accessories, shall be listed by Underwriters Laboratories, Inc. in <br /> their Electrical Construction Materials Catalog, and accepted for use on <br /> emergency systems. <br /> b. When conducting temperature rise tests to Paragraph 99 of UL-1008 the <br /> manufacturer shall include post-endurance temperature rise tests to verify the <br /> ability of the transfer switch to carry full rated current after completing the <br /> overload and endurance tests. j <br /> I <br /> C. Produce UL 1008 closing and withstand ratings for 3 cycles at 208 volts. <br /> Certified test reports from an independent testing laboratory to verify the <br /> identical samples have been-subject to three phase short circuit current at <br /> voltage indicated on drawings, for a minimum of 3 cycles duration, without <br /> contact damage or contact welding and without the use of current limiting fuse <br /> protection. Oscillograph traces are to be supplied to verify that the test <br /> parameters have been met. Withstand ratings shall not be series rated. <br /> i <br /> I <br /> Heartland Health Care Center of Zephyrhills-3181 16490-1 DE No 217032 j <br /> 38220 Henry Drive,Zephyrhills, FL 33542 Pending Emergency Rule 59A-4.1265 <br />
