About This Item

 

Full Description

Scope

This recommended practice is limited to auxiliary devices associated with motors operating in Division 2 areas, classified as Class I, Groups A, B, C, and D locations. This recommended practice is not an attempt to rewrite or otherwise supersede application sections of ANSI/NFPA 70-1990 [1], or any other codes or ordinances. Rather, it is intended to serve as a supplement to existing codes that in this area are not sufficiently specific to serve as a guide to good engineering practice. The guidance contained herein, therefore, is in addition to the ANSI/NFPA 70-1990 requirements for wiring systems for hazardous (classified) locations.

Purpose

The following information is intended to bring together a brief description of basic electrical practices in regard to the application and installation of auxiliary devices to motors operating in Class I, Groups A, B, C, and D, Division 2 locations It should be understood that this information is only a guide to promote consistent application of such devices and must be used with sound engineering judgment.

Abstract

Revision Standard - Superseded. Installation procedures and wiring methods and materials are recommended. Termination housings, motor surge protection, and power-factor-correction capacitors are discussed. The aim is to promote consistent application of the devices covered.
