Title
Switchgear - Medium Voltage Metal-Clad Assemblies - Conformance Test Procedure
National Electrical Manufacturers Association
Publication Date:
Jan 1, 2002
Scope:
This Standard is a conformance testing standard optionally applicable to all medium voltage metal-clad switchgear assemblies designed, tested, and manufactured in accordance with ANSI/IEEE C37.20.2, Metal-Clad Switchgear. This standard covers selected tests to demonstrate conformance with Section 6, Tests, of ANSI/IEEE C37.20.2. The requirements of ANSI/IEEE C37.20.2 are sufficient for application of medium voltage metal-clad switchgear assemblies, and conformance testing is not necessary to satisfy the basic requirements of ANSI/IEEE C37.20.2. Conformance testing is performed to show compliance with the basic requirements when it is required to satisfy special agreements or regulatory agency requirements. Conformance testing may be performed in association with the basic design testing if such testing is agreeable to those concerned; however, conformance testing is more likely to be performed some time after original development to satisfy a specific need. Conformance testing need not be performed if not required.
Purpose
This standard specifies the tests that shall be performed to demonstrate that the MC switchgear being tested conforms with the ratings assigned to it and meets the mechanical and electrical performance requirements specified in ANSI/IEEE C37.20.2.
