Consensus is established when, i

13、n the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and

14、 that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or

15、 procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American Nat

Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. Caution Notice: This American National Standard may be revised or withdrawn at any time. The

27、tandard has been developed to describe selected tests and procedures to demonstrate conformance in accordance with Section 5 of IEEE Standard for Indoor AC Medium-Voltage Switches for Use in Metal-Enclosed Switchgear, ANSI/IEEE C37.20.4. To facilitate its use and to permit timely revisions based on

28、experience, a separate document has been provided. This standard is one of several in a series of test procedures for conformance testing of switchgear products. Although this standard is written for general guidance, performance criteria are established so that this standard can be adopted as the b

29、asis for certification of indoor AC medium-voltage switches for use in metal-enclosed switchgear for nonutility installations subject to regulation by public authorities and similar agencies concerned with laws, ordinances, regulations, administrative orders, and similar instruments.

38、m-voltage switches rated above 1000 volts as designed, manufactured, and tested in accordance with ANSI/IEEE C37.20.4. It is intended for use in metal-clad switchgear, as described in ANSI/IEEE C37.20.2, and metal-enclosed interrupter switchgear, as described in ANSI/IEEE C37.20.3. Conformance testi

39、ng need not be performed but may be utilized to demonstrate that the switches conform with the ratings assigned, as agreeable to those concerned, usually some time after original design testing, to satisfy a specific need. This standard does not apply to installations under the exclusive control of

40、electric utilities for the generation, control, transformation, transmission, and distribution of electric energy located in buildings used exclusively by utilities for such purposes or located outdoors on property owned or leased by the utility or on public highways, streets, roads, and the like, o

NOTE 1An electric utility is an entity that is overseen by a public utility commission, a public service commission, or other regulatory agency having jurisdiction for such installations. NOTE 2Within this standard, the words “switch” or “switche

42、s“ shall be considered to mean “indoor ac medium-voltage switches for use in enclosures“ subject to the requirements of ANSI/IEEE C37.20.4. 2 Referenced and Related Standards 2.1 Referenced American National Standards This standard is intended to be used in conjunction with the following American Na
