Full Description
Scope
This document describes the methods and requirements for qualifying switchgear assemblies for indoor areas outside of the containment in nuclear power generating stations. These assemblies include: 1) Mettal-enclosed low-voltage power circuit breaker switchgear assemblies, as defined in ANSI/IEEE C37.20.1; 2) Metal-clad switchgear assemblies, as defined in ANSI/IEEE C37.20.2; 3) Metal-enclosed bus, as defined in ANSI/IEEE C37.23; 4) Metal-enclosed interrupter switchgear assemblies, as defined in ANSI/IEEE C37.20.3
Purpose
The purpose of this document is to provide amplification of the general requirements of ANSI/IEEE Std 323-1983 as they apply to the specific features of Class 1E switchgear assemblies. Where differences exist between this document and ANSI/IEEE Std 323-1983, this document takes precedence insofar as switchgear assemblies are concerned.
Abstract
New IEEE Standard - Superseded.This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. Methods and requirements for qualifying switchgear assemblies for indoor areas outside of the containment area in nuclear power generating stations are described. These assemblies include metal-enclosed low-voltage power circuit breaker switchgear assemblies, metal-clad switchgear assemblies, and metal-enclosed interrupter switchgear assemblies. This standard amplifies the general requirements of ANSI/IEEE 323-1983, IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations, as they apply to Class 1E switchgear assemblies.
