NATIONAL FOREWORD

This Indian Standard (Part 6) which is identical with IEC 61439-6 : 2012 ‘Low-voltage switchgear and controlgear assemblies — Part 6: Busbar trunking systems (busways)’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Low Voltage Switchgear and Controlgear Sectional Committee and approval of the Electrotechnical Division Council.

This standard is being adopted as part of the series. Other parts are:

Part 0 Guidance to specifying assemblies

Part 1 General rules

Part 2 Power switchgear and controlgear assemblies

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are however not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
